This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Harold F. Loomis rather than just read about it. In short: Harold Frederick Loomis (December 23, 1896 – July 5, 1976) was an American botanist and myriapodologist known for his contributions to agronomy, plant pathology, and millipede taxonomy. He worked for the U.S.

Key takeaways

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

Reference excerpt

Harold Frederick Loomis (December 23, 1896 – July 5, 1976) was an American botanist and myriapodologist known for his contributions to agronomy, plant pathology, and millipede taxonomy. He worked for the U.S. Department of Agriculture for over four decades, studying diseases of crop plants, and was a colleague of Orator F. Cook. He also made major contributions to the natural history of Central America and the West Indies, naming over 500 species of millipedes in total. He co-described with Cook the leggiest animal on earth: Illacme plenipes, with over 700 legs.

Biography Harold Loomis was born in the Mertensia neighborhood of Farmington, New York, in 1896. He worked for the U.S. Department of Agriculture from 1914 until his retirement in 1958, some 44 years, and was director of the U.S. Plant Introduction Station at Chapman Field, from 1931 to 1958. He was primarily involved in the production of natural rubber, and also worked on diseases of corn and cotton. He was a charter member of the Fairchild Tropical Botanic Garden, and served many years on its board of directors. He also collected plants and lichen from the American southwest, often contributing specimens along with botanist Robert Hibbs Peebles. in 1939 Loomis described the tropical palm tree Astrocaryum alatum ("Coquillo"). His other area of research was in arthropods. Loomis was an honorary research fellow in entomology at the Smithsonian Institution, and an active research collaborator with the National Museum of Natural History, and Florida State Collection of Arthropods in Gainesville. Early in his career he began working with fellow botanist/entomologist Orator F. Cook. In 1919 Loomis accompanied Cook on an expedition to China to study crops as well as collect millipedes, and in 1928 Loomis and Cook described the millipede with the greatest number of legs known, Illacme plenipes of California. With individuals possessing up to 750 legs (375 pairs), Illacme has more legs than any animal known. Loomis later described another species from Panama with 700 legs. Loomis's specialty was in the millipedes of Central America and the Caribbean, and over his career he named more than 500 species, at least 127 new genera, 2 new subfamilies, and 9 new families, including Messicobolidae, Tingupidae, and Tridontomidae, with only a few taxa named with co-authors. He produced 64 scientific papers on arthropods and 50 on millipedes. The eminent myriapodologist Richard L. Hoffman wrote of Loomis: "(H)is monographs on the faunas of Hispaniola (1936) and Panama (1964) stand out as oases in a desert of chaotic short descriptive papers. His 1968 checklist of the Mesamerican species is beyond praise for its fundamental reference value." In terms of numbers of species described, Loomis ranks as one of the ten most prolific millipede taxonomists in history.

Worked examples

Example 1 — a first encounter with Harold F. Loomis

Start with the simplest possible case. Write down what Harold F. Loomis claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 F. Loomis 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 F. Loomis 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 F. Loomis

In research
Harold F. Loomis appears in science 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 F. Loomis 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 F. Loomis is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1896 births, 1976 deaths, 20th-century American agronomists, so understanding it makes those chapters shorter.
In everyday life
Look for Harold F. Loomis 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.
