Key takeaways

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

Reference excerpt

Leland Ossian Howard (June 11, 1857 – May 1, 1950) was a pioneer American entomologist who worked in the US Department of Agriculture. Serving as the chief of the bureau of entomology, a successor to C.V. Riley, he helped establish economic entomology as a profession in the United States and strengthened research activities, helping establish laws to prevent the introduction of agricultural pests. He was a specialist on the parasitic wasp family Chalcididae, and contributed to the introduction of biological control agents for pest management. Howard also took an interest in medical entomology.

Early life Howard was born to Ossian Gregory Howard, a lawyer, and Lucy Denham Thurber on 11 June 1857. His relatives from his mother's side included the Harvard astronomer E.C. Pickering while other distant relatives included Senator J.M. Howard and President William Howard Taft. Shortly after his birth, the family moved from Rockford, to Ithaca, New York where his father worked with a law firm. An interest in insect collecting was encouraged by his parents with the gift of The Butterfly Hunters by Mary Treat at the age of 10, followed by more books. At the age of 13, along with another collector friend, he recorded the introduction of the European cabbage butterfly (Pieris rapae) in the Catskill region. Howard attended Ithaca Academy. Along with his friends, he founded the Ithaca Natural History Society to meet and discuss papers and insects. While out collecting one day, Howard met John Henry Comstock, who invited him to his lab at Cornell University. Howard enrolled in Cornell in September 1873, three years after the death of his father, and following the advice of his mother's friends, went to study civil engineering. Doing poorly in differential calculus made him drop engineering and he began to study other subjects including French, German, and Italian. He then joined Comstock's lab as the first research student and graduated in June 1877 with a thesis on respiration in the larva of Corydalis cornutus. Howard worked with Burt Green Wilder and Simon Henry Gage and received a masters at Cornell. In the 1880s, Howard also attended Columbian College (now George Washington University) for medicine, although he didn't complete a degree. He however received an honorary MD from the same university in 1911 for his contributions to medical entomology.

Career

In July 1878, on the recommendation of Professor Comstock, Howard applied for a post in the U.S. Department of Agriculture as an assistant entomologist to C.V. Riley. Despite the low salary ($100/month) and advice against joining it from many friends and family, he took up the job. Among his first tasks was to prepare a manual on sericulture which was published with Riley as the author. Riley was briefly replaced by Professor Comstock in 1880, and again many of his writings went under the authorship of Comstock. This was accepted practice after Riley's return in 1881, until Howard changed it when he rose to authority and ensured that all his co-workers were appropriately credited. When Riley died in a bicycle accident in 1894, Howard became chief of the Bureau of Entomology. He held the position until 1 October 1927. He continued to consult for the Bureau until officially retiring on 30 June 1931. He worked on the systematics of the parasitic Hymenoptera, biological control, and medical entomology of mosquitoes and other flies. Howard was the editor of Insect Life, a lecturer on entomology at several colleges and universities, and a contributor to reference books on the subject of entomology. He was made permanent secretary of the American Association for the Advancement of Science, honorary curator in the United States National Museum, and consulting entomologist of the Public Health Service. He was elected to the American Philosophical Society in 1911, the American Academy of Arts and Sciences in 1913, and the National Academy of Sciences in 1916. Since 1907, he was a Fellow of the Entomological Society of America.

Personal life Howard married Marie T. Clifton in 1886, "a girl with a glorious soprano voice", who he met while singing in a choir at college. They had three daughters. Howard was known for his interests in sports.

Worked examples

Example 1 — a first encounter with Leland Ossian Howard

Start with the simplest possible case. Write down what Leland Ossian Howard claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Leland Ossian Howard 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 Leland Ossian Howard 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 Leland Ossian Howard

In research
Leland Ossian Howard appears in astronomy 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 Leland Ossian Howard 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
Leland Ossian Howard is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1857 births, 1950 deaths, 19th-century American science writers, so understanding it makes those chapters shorter.
In everyday life
Look for Leland Ossian Howard 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.
