Ernest Everett Just (August 14, 1883 – October 27, 1941) was a pioneering African-American biologist, academic and science writer. Just's primary legacy is his recognition of the fundamental role of the cell surface in the development of organisms. In his work within marine biology, cytology and parthenogenesis, he advocated the study of whole cells under normal conditions, rather than simply breaking them apart in a laboratory setting.

Biologist Scientist studying living organisms

A biologist is a scientist who has specialized knowledge in the field of biology, the scientific study of life. Biologists involved in fundamental research attempt to explore and further explain the underlying mechanisms that govern the functioning of living matter. Biologists involved in applied research attempt to develop or improve more specific processes and understanding, in fields such as medicine and industry.

Marine biology The scientific study of organisms that live in the ocean

Marine biology is the scientific study of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.

Cell biology scientific discipline that studies cells

Cell biology is a branch of biology that studies the structure and function of the cell, which is the basic unit of life. Cell biology is concerned with the physiological properties, metabolic processes, signaling pathways, life cycle, chemical composition and interactions of the cell with their environment. This is done both on a microscopic and molecular level as it encompasses prokaryotic cells and eukaryotic cells. Knowing the components of cells and how cells work is fundamental to all biological sciences; it is also essential for research in bio-medical fields such as cancer, and other diseases. Research in cell biology is closely related to genetics, biochemistry, molecular biology, immunology and cytochemistry.

Early life

Ernest Everett Just was born in South Carolina to Charles Jr. and Mary Matthews Just on August 14, 1883. His father and grandfather, Charles Sr., were builders. When Ernest was four years old, both his father and grandfather died (the former of alcoholism). [1] Just's mother became the sole supporter of Just, his younger brother, and his younger sister. Mary Matthews Just taught at an African-American school in Charleston to support her family. During the summer, she worked in the phosphate mines on James Island. Noticing that there was much vacant land near the island, Mary persuaded several black families to move there to farm. The town they founded, now incorporated in the West Ashley area of Charleston, was eventually named Maryville in her honor. [2]

South Carolina State of the United States of America

South Carolina is a state in the Southeastern United States and the easternmost of the Deep South. It is bordered to the north by North Carolina, to the southeast by the Atlantic Ocean, and to the southwest by Georgia across the Savannah River.

Charleston, South Carolina City in the United States

Charleston is the oldest and largest city in the U.S. state of South Carolina, the county seat of Charleston County, and the principal city in the Charleston–North Charleston–Summerville Metropolitan Statistical Area. The city lies just south of the geographical midpoint of South Carolina's coastline and is located on Charleston Harbor, an inlet of the Atlantic Ocean formed by the confluence of the Ashley, Cooper, and Wando rivers. Charleston had an estimated population of 136,208 in 2018. The estimated population of the Charleston metropolitan area, comprising Berkeley, Charleston, and Dorchester counties, was 787,643 residents in 2018, the third-largest in the state and the 78th-largest metropolitan statistical area in the United States.

Phosphate salt or ester of phosphoric acid

A Phosphate is a chemical derivative of phosphoric acid. The phosphate ion (PO
4
)3−
is an inorganic chemical, the conjugate base that can form many different salts. In organic chemistry, a phosphate, or organophosphate, is an ester of phosphoric acid. Of the various phosphoric acids and phosphates, organic phosphates are important in biochemistry and biogeochemistry, and inorganic phosphates are mined to obtain phosphorus for use in agriculture and industry. At elevated temperatures in the solid state, phosphates can condense to form pyrophosphates.

When Just was young, he became severely sick for six weeks with typhoid. Once the fever passed, he had a hard time recuperating, and his memory had been greatly affected. He had previously learned to read and write, but now had to relearn. His mother had been very sympathetic in teaching him but after a while, she gave up on him. Then one day, he read his first page by himself, this seemed miraculous. He kept his new secret to himself for a month before telling his mother because he felt she had hurt him with her unreasonable expectations. [3]

Hoping Just would become a teacher, at the age of 13 his mother sent him to the "Colored Normal Industrial Agricultural and Mechanical College of South Carolina", the only 1890 land grant school for the education of Negros in South Carolina, later known as South Carolina State University Orangeburg, South Carolina. Believing that schools for blacks in the south were inferior, Just and his mother thought it better for him to go north. At the age of 16, Just enrolled at the Meriden, New Hampshire, college-preparatory high school Kimball Union Academy. During Just's second year at Kimball, he returned home for a visit only to learn that his mother had been buried an hour before he arrived. [3] Despite this hardship, Just completed the four-year program in only three years and graduated in 1903 with the highest grades in his class. [4]

Southern United States Cultural region of the United States

The southern United States, also known as the American South, Dixie, or simply the South, is a region of the United States of America. It is located between the Atlantic Ocean and the western United States, with the midwestern United States and northeastern United States to its north and the Gulf of Mexico and Mexico to its south.

Just went on to graduate magna cum laude from Dartmouth College in Hanover, New Hampshire. [5] Just won special honors in zoology, and distinguished himself in botany, history, and sociology as well. He was also honored as a Rufus Choate scholar for two years and was elected to Phi Beta Kappa. [4] Just was also a candidate to deliver a commencement speech, but was not chosen because the faculty "decided it would be a faux pas to allow the only black in the graduating class to address the crowd of parents, alumni, and benefactors. It would have made too glaring the fact that Just had won just about every prize imaginable." [3]

Dartmouth College private liberal arts university in Hanover, New Hampshire, United States

Dartmouth College is a private Ivy League research university in Hanover, New Hampshire, United States. Established in 1769 by Eleazar Wheelock, it is the ninth-oldest institution of higher education in the United States and one of the nine colonial colleges chartered before the American Revolution. Although founded as a school to educate Native Americans in Christian theology and the English way of life, Dartmouth primarily trained Congregationalist ministers throughout its early history. The university gradually secularized, and by the turn of the 20th century it had risen from relative obscurity into national prominence as one of the top centers of higher education.

Hanover, New Hampshire Town in New Hampshire, United States

Hanover is a town along the Connecticut River in Grafton County, New Hampshire, United States. The population was 11,260 at the 2010 census. Dartmouth College and the US Army Corps of Engineers Cold Regions Research and Engineering Laboratory are located in Hanover. The Appalachian Trail crosses the town.

Botany science of plant life

Botany, also called plant science(s), plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word βοτάνη (botanē) meaning "pasture", "grass", or "fodder"; βοτάνη is in turn derived from βόσκειν (boskein), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists study approximately 410,000 species of land plants of which some 391,000 species are vascular plants, and approximately 20,000 are bryophytes.

Founding of Omega Psi Phi

On November 17, 1911, Ernest Just and three Howard University students (Edgar Amos Love, Oscar James Cooper, and Frank Coleman), established the Omega Psi Phi fraternity on the campus of Howard. Love, Cooper, and Coleman had approached Just about establishing the first black fraternity on campus. Howard's faculty and administration initially opposed the idea of establishing the fraternity, fearing that it could pose a political threat to Howard's white administration. However, Just worked to mediate the controversy and, despite the initial doubts, Omega Psi Phi, Alpha Chapter, was chartered on Howard's campus on December 15, 1911. Omega Psi Phi was incorporated under the laws of the District of Columbia on October 28, 1914. [1]

Omega Psi Phi historically Black fraternity

Omega Psi Phi (ΩΨΦ) is an international fraternity with over 750 undergraduate and graduate chapters. The fraternity was founded on November 17, 1911 by three Howard University juniors, Edgar Amos Love, Oscar J. Cooper and Frank Coleman, and their faculty adviser, Dr. Ernest Everett Just. Omega Psi Phi is the first predominantly African-American fraternity to be founded at a historically black university.

Career

When he graduated from Dartmouth, Just faced the same problems as all black college graduates of his time: no matter how brilliant they were or how high were their grades, it was almost impossible for blacks to become faculty members at white colleges or universities. Just took what seemed to be the best choice available to him and accepted a teaching position at historically black Howard University in Washington, D.C. In 1907, Just first began teaching rhetoric and English, fields somewhat removed from his specialty. By 1909, however, he was teaching not only English but also Biology. [6] In 1910, he was put in charge of a newly formed biology department by Howard's president, Wilbur P. Thirkield and, in 1912, he became head of the new Department of Zoology, a position he held until his death in 1941. Not long after beginning his appointment at Howard, Just was introduced to Frank R. Lillie, the head of the Department of Zoology at the University of Chicago. Lillie, who was also director of the Marine Biological Laboratory (MBL) at Woods Hole, Massachusetts, invited Just to spend the summer of 1909 as his research assistant at the MBL. During this time and later, Just's experiments focused mainly on the eggs of marine invertebrates. He investigated the fertilization reaction and the breeding habits of species such as Platynereis megalops , Nereis limbata , and Arbacia punctulata . For the next 20 or so years, Just spent every summer but one at the MBL. On June 12, 1912, he married Ethel Highwarden, who taught German at Howard University. They had three children: Margaret, Highwarden, and Maribel.

While at the MBL, Just learned to handle marine invertebrate eggs and embryos with skill and understanding, and soon his expertise was in great demand by both junior and senior researchers alike. [7] In 1915, Just took a leave of absence from Howard to enroll in an advanced academic program at the University of Chicago. That same year, Just, who was gaining a national reputation as an outstanding young scientist, was the first recipient of the NAACP's Spingarn Medal, which he received on February 12, 1915. The medal recognized his scientific achievements and his “foremost service to his race." [3] He began his graduate training with coursework at the MBL: in 1909 and 1910 he took courses in invertebrate zoology and embryology, respectively, there. His coursework continued in-residence at the University of Chicago. His duties at Howard delayed the completion of his coursework and his receipt of the Ph.D. degree. [7] However, in June 1916, Just received his degree. It was in zoology, with a thesis on the mechanics of fertilization. Just thereby became one of only a handful of blacks who had gained the doctoral degree from a major university. By the time he received his doctorate from Chicago, he had already published several research articles, both as a single author and a co-author with Lillie. [6] During his tenure at Woods Hole, Just rose from student apprentice to internationally respected scientist. A careful and meticulous experimentalist, he was regarded as "a genius in the design of experiments." [8]

Just, however, became frustrated because he could not obtain an appointment at a major American university. He wanted a position that would provide a steady income and allow him to spend more time with his research. Just's scientific career involved a constant struggle for an opportunity for research, "the breath of his life". He was condemned by race to remain attached to Howard, an institution that could not give full opportunity to ambitions such as the ones Just had. [7] In 1929, Just traveled to Naples, Italy, where he conducted experiments at the prestigious zoological station "Anton Dohrn". Then, in 1930, he became the first American to be invited to the Kaiser Wilhelm Institute in Berlin-Dahlem, Germany, where several Nobel Prize winners carried out research. Altogether from his first trip in 1929 to his last in 1938, Just made ten or more visits to Europe to pursue research. Scientists treated him like a celebrity and encouraged him to extend his theory on the ectoplasm to other species. [7] Just enjoyed working in Europe because he did not face as much discrimination there in comparison to the U.S. and when he did encounter racism, it invariably came from Americans. [3] Beginning in 1933, when the Nazis began to take the control of the country, Just ceased his work in Germany. He later moved his European-based studies to Paris and to the marine laboratory at the French fishing village of Roscoff, located on the English channel.

Just authored two books, Basic Methods for Experiments on Eggs of Marine Animals (1939) and The Biology of the Cell Surface (1939), and he also published at least seventy papers in the areas of cytology, fertilization and early embryonic development. [9] He discovered what is known as the fast block to polyspermy; he further elucidated the slow block, which had been discovered by Fol in the 1870s; and he showed that the adhesive properties of the cells of the early embryo are surface phenomena exquisitely dependent on developmental stage. [10] He believed that the conditions used for experiments in the laboratory should closely match those in nature; in this sense, he can be considered to have been an early ecological developmental biologist. [11] His work on experimental parthenogenesis informed Johannes Holtfreter's concept of "autoinduction" [12] which, in turn, has broadly influenced modern evolutionary and developmental biology. [13] His investigation of the movement of water into and out of living egg cells (all the while maintaining their full developmental potential) gave insights into internal cellular structure that is now being more fully elucidated using powerful biophysical tools and computational methods. [14] [15] [16] [17] These experiments anticipated the non-invasive imaging of live cells that is being developed today. Although Just's experimental work showed an important role for the cell surface and the layer below it, the "ectoplasm," in development, it was largely and unfortunately ignored. [3] [18] This was true even with respect to scientists who emphasized the cell surface in their work. It was especially true of the Americans; with the Europeans, he fared somewhat better. [7]

Death

At the outbreak of World War II, Just was working at the Station Biologique in Roscoff, researching the paper that would become Unsolved Problems of General Biology. Although the French government requested foreigners to evacuate the country, Just remained to complete his work. In 1940, Germany invaded France and Just was briefly imprisoned in a prisoner-of-war camp. With the help of the family of his second wife, a German citizen, he was rescued by the U.S. State Department and he returned to his home country in September 1940. However, Just had been very ill for months prior to his encampment and his condition deteriorated in prison and on the journey back to the U.S. In the fall of 1941, he was diagnosed with pancreatic cancer, and died shortly thereafter. [19]

Legacy

Just was the subject of the 1983 biography Black Apollo of Science: The Life of Ernest Everett Just by Kenneth R. Manning. The book received the 1983 Pfizer Award and was a finalist for the 1984 Pulitzer Prize for Biography or Autobiography. [20] [21] In 1996, the U.S. Postal Service issued a commemorative stamp honoring Just. [22]

Beginning in 2000, the Medical University of South Carolina has hosted the annual Ernest E. Just Symposium to encourage non-white students to pursue careers in biomedical sciences and health professions. [23] In 2008, a National Science Foundation-funded symposium honoring Just and his scientific work was held on the campus of Howard University, where he was a faculty member from 1907 until his death in 1941. Many of the speakers at the symposium contributed papers to a special issue of the journal Molecular Reproduction and Development dedicated to Just that was published in 2009. Since 1994 the American Society for Cell Biology has given an award [24] and hosted a lecture in Just's name. At least two of the institutions with which Just was associated have established prizes or symposia in his name: The University of Chicago, where Just received his PhD (in zoology, in 1916), and Dartmouth College, where he received his undergraduate degree. In 2013, an international symposium honoring Just was held at the Stazione Zoologica Anton Dohrn in Naples, Italy, where Just had worked starting in 1929. [25] [26] [27] [28]

In 2002, scholar Molefi Kete Asante included Just on his list of the 100 Greatest African Americans . [29] A children's book about Just, titled The Vast Wonder of the World: Biologist Ernest Everett Just, written by Mélina Mangal and illustrated by Luisa Uribe, was published by Millbrook Press in November 2018.

Just believed that "life as an event lies in a combination of chemical stuffs exhibiting physical properties; and it is in this combination, i.e., its behavior and activities, and in it alone that we can seek life.". [30] He also wrote: "[L]ife is the harmonious organization of events, the resultant of a communion of structures and reactions", [10] and "We [scientists] have often striven to prove life as wholly mechanistic, starting with the hypothesis that organisms are machines! Living substance is such because it possesses this organization--something more than the sum of its minutest parts" [31] He argued forcefully that the "ectoplasm," the outer region of the cytoplasm, and not the nucleus, constitutes the heart of the dynamic cell. He was convinced that the surface of the egg cell possesses an "independent irritability," which enables the egg (and all cells) to respond productively to diverse stimuli. [32]
