Herndon, Elisabeth Chapline

Sarah Elisabeth Chapline Herndon was the only volunteer Red Cross nurse from Arkansas to serve in the Spanish-American War. Elisabeth Chapline was born on April 4, 1871, near Sweet Home (Pulaski County) to William Heros Chapline and Mary Murray Chapline. Her father was a landowner and planter. She had one brother and two sisters. Chapline attended the Arkansas Female College in Little Rock (Pulaski County) and nursing school at Chicago Baptist Hospital in Illinois. When war broke out in 1898, Chapline was too young for enlistment but was admitted as a contract nurse. She served in Fernandina, Florida, and at Camp Cuba Libre in Panama City, Florida. She was one of 1,700 volunteer nurses to serve in the war. Chapline …

Herrings

aka: Clupeids
Herrings (Order Clupeiformes) belong to a large family (Clupeidae) of about 200 species within fifty-four genera of cosmopolitan ray-finned fishes that are mostly marine; a few inhabit freshwater, and some are anadromous—that is, they migrate up rivers from saltwater habitats for purposes of spawning. The family includes herrings, menhadens, sardines, and shads. Most herrings are small fishes, generally being less than 300 mm (12 in.), but some may reach 750 mm (30 in.). Many are valuable food fishes and are collected for production of fish meal and oil, protein concentrate, and fertilizer. Some commercially important species include Atlantic herring (Clupea harengus) found in the north Atlantic, Pacific sardine (Sardinops sagax), and Atlantic menhaden (Brevortia tyrannus). In the fossil record, clupeid …

Hodges, Thomas L.

Thomas Luther Hodges was a noted physician and amateur archaeologist in Hot Spring County in the early twentieth century. Focusing on materials related to the late prehistoric Caddo, the collection accumulated by Hodges and his wife, Charlotte, is now held by the Joint Educational Consortium in Arkadelphia (Clark County). Thomas L. Hodges was born in Morehead, Kentucky, on January 17, 1868. It is unclear what happened to Hodges’s birth parents, but he became the adopted son of William and Sarah Hodges and moved with his adoptive family to Knox County, Missouri, in the early 1870s. His father died in 1874, and Sarah Hodges remarried the following year to widower George Sloan. In the 1880 federal census, Hodges appears with his …

Hookworm Eradication

Hookworm disease was a significant public health issue in Arkansas until the movement to eradicate hookworms in the early twentieth century. With official estimates claiming that up to twenty percent of the entire population of the state suffered from hookworm infestation, this parasite was sufficiently widespread to affect the economy as well as the health of Arkansas. Its virtual eradication was the result of a public health and education campaign on the part of the Rockefeller Sanitary Commission between 1910 and 1914. The hookworm is an intestinal parasite that grows and reproduces in the intestines of its hosts. When infected people deposit feces containing hookworm eggs in warm, moist, shaded soil, the eggs hatch and develop into larvae. Within five …

Hooper, Philo Oliver

Philo Oliver Hooper has been called the father of Arkansas medicine. He was one of the founders of the Medical Department of Arkansas Industrial University, now the University of Arkansas for Medical Sciences (UAMS), a founder and the first president of the Arkansas State Medical Association, a founding board member and director of the Arkansas Lunatic Asylum, and vice president of the American Medical Association. P. O. Hooper was born on October 11, 1833, in Little Rock (Pulaski County) to Alanson Hooper and Magdaline Perry Hooper. After obtaining what education was available in the city at the time, he pursued his education at Nashville University in Nashville, Tennessee. Returning home to Little Rock, he found employment as the chief clerk …

Hoover, Dorothy M.

aka: Dorothy Estheryne McFadden Clarke Hoover
Dorothy M. Hoover was a pioneer in the field of aeronautical mathematics and physics. The granddaughter of enslaved people, she overcame the significant obstacles facing African American women in the Jim Crow era of the twentieth century to earn advanced degrees in mathematics and physics. One of her greatest achievements in aeronautical research was her contribution to the development of the “thin sweptback tapered wing,” which revolutionized flight and became the aviation industry standard. Her life story was essentially unknown until she was briefly mentioned in the highly acclaimed book Hidden Figures: The American Dream and the Untold Story of the Black Women Mathematicians Who Helped Win the Space Race (2016), by Margot Lee Shetterly. Hidden Figures, which was made …

Hospital Unit T

When the United States entered World War I on April 6, 1917, the need for trained medical personnel was great, and medical units of doctors, nurses, and enlisted men were recruited heavily. The American Red Cross asked for units to be formed from hospitals and medical schools across the United States to go to France and England. Arkansas’s contribution was Hospital Unit T, Medical Department, National Army (called Hospital Unit T for short). Dr. William A. Snodgrass, a Little Rock (Pulaski County) physician with the University of Arkansas Medical School (now the University of Arkansas for Medical Sciences) was authorized to form a unit for military service. His authorization was announced in the Arkansas Gazette on July 1, 1917. This …

Hospitals (Civil War)

A wide range of Civil War hospitals in Arkansas included field hospitals established in the immediate aftermath of battle, commandeered houses and churches, and somewhat permanent post hospitals in occupied areas. Union bases tended to have more purpose-built hospital facilities, while Confederate doctors made use of any available buildings, such as colleges, hotels, churches, and private homes. The need for hospital facilities became obvious soon after Arkansas seceded from the Union and the new Confederate recruits became ill from the myriad diseases that afflicted their camps. Hospitals were established wherever large groups of troops gathered, often treating soldiers from specific regiments or from the same states. In early 1862, for instance, Confederate forces in Washington County established the Mount Comfort …

Hot Springs Medical Journal

In the late nineteenth and early twentieth centuries, Hot Springs (Garland County) was home to the Hot Springs Medical Journal, first published in January 1892. Although medical journals were published in nearby locations including Little Rock (Pulaski County), Memphis, Tennessee, and St. Louis, Missouri, the founders of the publication felt that the natural hot springs for which the city was named provided a great resource for many patients. They stated in the first volume: “The city of Hot Springs, Arkansas is…the greatest sanitarium on earth, and in a few years is inevitably destined to become the most universally frequented health resort in the world.” At that time, Hot Springs was already quite a tourist area. The resident population was 15,000, …

Hot Springs Smallpox Outbreak of 1895

In the early months of 1895, Hot Springs (Garland County) suffered through a blizzard, numerous fires, and a smallpox outbreak. These collective disasters left the community economically crippled. The Blizzard of 1895 that swept across much of the country in late January/early February had made travel to the spa resort town impossible during what was normally its busy season. By mid-February, travel had resumed, and visitors soon filled up the town. Then, a series of unexplained fires started flaring up across the city, culminating in a large conflagration in the early hours of Friday, February 22. The fire started around 3:30 a.m. and, within minutes, it had engulfed four and a half blocks of businesses and residential buildings while thousands …

Houser, Napoleon Bonaparte

Napoleon Bonaparte Houser was a prominent African American physician, owner of the Black Diamond Drug Store, and investor in Helena (Phillips County) from 1901 to 1920. He came to Helena from Charlotte, North Carolina, as the Arkansas Delta’s population and opportunities grew, but returned to the place of his birth following the Elaine Massacre. N. B. Houser was born near Gastonia, in Gaston County, North Carolina, on February 14, 1869. He was the son of William H. Houser, a well-to-do brick mason and contractor, and Fannie Houser, a housekeeper and mother. The youngest of six siblings, Houser attended public schools in Charlotte and worked as a farm hand on his father’s farm until the age of fourteen, when he began …

Huddleston, John Wesley

John Wesley Huddleston is best known as a struggling farmer who found two diamonds on the surface of his field near Murfreesboro (Pike County) in August 1906 and made himself and his state famous. Soon after the discovery, he was recognized as the first person outside South Africa to find diamonds at an original volcanic source. In the process, he also became the controversial subject of numerous folk tales. A native of Pike County, John Huddleston was born in 1862 to David Fielding Huddleston and America White Huddleston. He had seven siblings before his mother’s death in the early 1870s and gained three step-sisters after his father’s remarriage to Francis Carey. In 1886, Huddleston wed Sarah A. Keys, the mother …

Human Development Centers

From 1888 to 1959—prior to the creation of human development centers (HDCs)—the Arkansas State Hospital provided long-term care to individuals with intellectual disabilities as well as to individuals with severe mental illness. Arkansas lagged behind other states in development of facilities specializing in the care of the intellectually disabled. In the mid-1950s, plans were set in motion to develop a facility that would specialize in the treatment and education of children with intellectual disabilities. Within one year of the opening of the Arkansas Children’s Colony (later renamed the Conway Human Development Center) in 1959, the facility received accolades for its physical construction as well as for its progressive curriculum for residents. Soon after, several other Southern states were following in …

Human Dissection Monument

The first human dissection performed in Arkansas is commemorated by an obelisk located at the edge of MacArthur Park in Little Rock (Pulaski County). In 1927, the Arkansas Medical Society unveiled the marker, whose inscription states that the dissection was held on that spot in November 1874. To clarify: the monument honors the state’s first such legal event, and the unveiling took place on May 13, despite the marker being dated May 12. Following appeals by doctors, in April 1873 the Arkansas General Assembly passed Act 45 authorizing “dissection in certain cases for the advancement of science.” This paved the way for the establishment of a medical school, as the new law gave both doctors and medical students the right …

Hunter, Carl Glenn

Conservationist Carl Glenn Hunter achieved prominence in two branches of the Arkansas outdoors—its fauna and its flora. Activities with wildflowers of the state made him a household name in Arkansas and beyond after his retirement as a wildlife biologist. Carl Hunter was born on August 30, 1923, in Little Rock (Pulaski County). He graduated from Little Rock High School (now Central High School) in 1941 and received a bachelor of science in agriculture degree from the University of Arkansas (UA) in Fayetteville (Washington County) in 1945. In college, Hunter worked part time for the Arkansas Game and Fish Commission (AGFC); he became a full-time employee in July 1945. He was one of the first hires of the agency after it …

Hydroelectricity

Hydroelectric power is the electricity generated by the gravitational force of falling or flowing water through a turbine connected to a power generator. The three major types of hydropower facilities include reservoirs (high dams), in-stream (low dams), and pumped-storage. The most common type is the high dam, which creates significant reservoirs behind the dam (e.g., Hoover Dam). In 1882, the world’s first hydroelectric power station, located in Appleton, Wisconsin, produced 12.5 kilowatts of electrical power. Also in the early 1880s, a similar facility opened in New York City. Since these early facilities, hydroelectric power from the nation’s waterways has proliferated. Hydroelectric development in Arkansas can generally be grouped into three time periods—1924–1930; 1944–1973; and 1988–1999—and under three sponsoring agencies: Arkansas …

Hymenoptera

aka: Ants
aka: Bees
aka: Wasps
Hymenopterans belong to the Phylum Arthropoda, Subphylum Labiata, Superclass Hexapoda, Class Insecta, and Order Hymenoptera. It is a large order of insects with over 150,000 described species comprising the sawflies, woodwasps, ichneumonids, chalcids, wasps, bees, and ants. In addition, there are over 2,000 extinct taxa. The order ranks third in the top five orders of insects in terms of total number of species. Many examples of this order are found in Arkansas, including the invasive fire ant. The Hymenoptera are divided into two suborders: the Symphyta (which have no waist) and the Apocrita (which have a narrow waist). Symphytans include the horntails, sawflies, and parasitic wood wasps. They have an unconstricted junction between the thorax and abdomen and a serrated …

Ictaluridae

aka: Catfishes
aka: Bullheads
aka: Madtoms
The Ictaluridae is a family of North American native fishes belonging to the Class Siluriformes. The Ictaluridae family also belongs to the Superorder Ostariophysi, the second-largest superorder of fish. This diverse group, present on all continents except Antarctica, contains 10,758 species—more than twenty-eight percent of known fish species in the world and seventy-two percent of all freshwater species. The family proper includes about seven genera and fifty-one species, some commonly known as bullheads, catfishes, and madtoms. As such, it is the largest family of freshwater fishes endemic to North America. In Arkansas, they are easily recognized as the only fishes in the state with four pairs (two on the snout, two on the end of maxillae, and four on the …

Information Galore

aka: Infogo
Information Galore, Inc., (a.k.a. Infogo) of El Dorado (Union County) was the first commercial Internet service provider (ISP) in Arkansas. Although the company was short-lived, it had a notable impact upon economic and educational initiatives in southern Arkansas, as well as parts of Texas and Louisiana. Infogo was founded by six individuals. John Gray was a world-famous geologist who was appointed to serve on the Arkansas Geological Commission (now Arkansas Geological Survey) several times by Governor Bill Clinton and who did work for the United Nations. Gray, along with Watt McKinney, Leon Wood, William L. (Billy) Cook, and Robert McKinney each invested $5,000. Joe Brazeal was a board member of ARKnet, the state’s educational computer network, and provided technical expertise …

Insects

Insects account for over half of all species described thus far worldwide, and they are the dominant form of life in terrestrial environments. It is estimated that 35,000 to 40,000 species of insects live in Arkansas, including around 10,000 species of beetles, around 9,000 species of flies, nearly 8,000 species of bees and wasps, and around 5,000 species of moths and butterflies. The remainder make up small orders such as the bristletails, mayflies, dragonflies and damselflies, cockroaches, mantids, termites, stoneflies, grasshoppers and crickets, earwigs, stick insects, book and bark lice, chewing and sucking lice, and true bugs and lacewings and their relatives. It is still not uncommon to find species in Arkansas that are unnamed and new to the scientific …

Instructional Microcomputer Project for Arkansas Classrooms (IMPAC)

The Instructional Microcomputer Project for Arkansas Classrooms (IMPAC) was an innovative program that helped make emerging microcomputer technologies a key component of education in Arkansas. Influential across the nation, IMPAC was cited for excellence by Electronic Learning, Instructor Magazine, Pro Education, Information Week, the National Governors Association, the Congressional Office of Technology Assessment, Nelson B. Heller & Associates, and the Southwest Education Development Laboratory. A number of Arkansas educators made significant efforts in laying a foundation for the use of microcomputers in instruction, as well as providing for technical support and workshops for teachers and school administrators, K–12. New technologies of the 1980s included networking microcomputers, the progression toward online resources, computer-assisted instruction and multimedia, and instructional management software for …
