Harold Amos

Harold Amos is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Harold Amos rather than just read about it. In short: Harold Amos (September 7, 1918 – February 26, 2003) was an American microbiologist. He taught at Harvard Medical School for nearly fifty years and was the first African American department chair of the school.

Key takeaways

  • Harold Amos belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Harold Amos to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Harold Amos from memory before moving on to harder problems.

Reference excerpt

Harold Amos (September 7, 1918 – February 26, 2003) was an American microbiologist. He taught at Harvard Medical School for nearly fifty years and was the first African American department chair of the school.

Early life Amos was born in Pennsauken Township, New Jersey, to Howard R. Amos Sr., a Philadelphia postman, and Iola Johnson. He was the second of nine children. Iola Johnson was adopted and educated by a Philadelphia Quaker family. Due to the close relationship between Iola and the Quaker family, the Amos family received many books, including a biography of Louis Pasteur. Excelling as a student, Amos graduated in 1936 at the top of his class from Camden High School in New Jersey. He attended Springfield College in Massachusetts on a full academic scholarship. In 1941 he graduated summa cum laude with a degree in biology. He was drafted the following year, and after returning home from World War II in 1946, Amos began his graduate studies at Harvard University. He was the first African American to earn a doctoral degree from the Division of Medical Sciences, Harvard Medical School, in 1952.

Military service Amos was drafted into the US Army in 1942, serving in the Quartermaster's Corps in World War II as a warrant officer. He started out his military service in England before being sent to France six days following the battle of Normandy. There, he traveled along the coast of France where he eventually started speaking very fluently in the language while becoming an expert on the local food and wine. He was discharged in February 1946, after which he started his career in microbiology.

Career In September 1947, Springfield College hired him as a biology professor. Amos was the college’s first African American faculty member. Amos was awarded a M.A. in 1947 and a Ph.D. in 1952 from Harvard Medical School. He was a graduate student with Howard J. Mueller. Harold's thesis was on the infectivity of the Herpes virus. After graduating, he was awarded a Fulbright scholarship that took him to the Pasteur Institute for two years. Amos joined the Harvard Medical School faculty in 1954, working as a teacher. He was the chairman of the bacteriology department from 1968 to 1971 and again from 1975 to 1978. In 1975, he was named the Maude and Lillian Presley professor of microbiology and molecular genetics. He was a presidential advisor to Richard Nixon, a Fellow of the American Academy of Arts and Sciences (1974), the Institute of Medicine, and the American Association for the Advancement of Science. In 1988 Amos received professor emeritus status. Amos was awarded the National Academy of Sciences' Public Welfare Medal in 1995 and the Harvard Centennial Medal in 2000. He directed the Minority Medical Faculty Development Program (MMFDP) of the Robert Wood Johnson Foundation after his retirement from Harvard. A diversity award at Harvard Medical School is named after Amos. He inspired hundreds of minorities to become medical doctors. He was well known as an inviting and welcoming mentor to both students and junior faculty members.

Publications Harold Amos research was mostly recognized for his work about bacterial metabolism, nutrition, animal cell culture, virology, and the effects of hormones. During his time at Harvard University he began working on a thesis on herpes simplex virus that utilized chickens' chorioallantoic membrane, which led to his Fulbright Fellowship. That fellowship supported his work on mutation of E. coli and his research on using cells in culture to understand how molecule entry is regulated in cells. Amos published over seventy scientific papers.

Worked examples

Example 1 — a first encounter with Harold Amos

Start with the simplest possible case. Write down what Harold Amos claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Harold Amos before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Harold Amos ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Harold Amos

In research
Harold Amos appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Harold Amos in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Harold Amos is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1918 births, 2003 deaths, 20th-century African-American scientists, so understanding it makes those chapters shorter.
In everyday life
Look for Harold Amos outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
