Harold Harrington

Harold Harrington is a astronomy 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 Harrington rather than just read about it. In short: Harold David Harrington (March 14, 1903 – January 22, 1981) was an American botanist who specialized in flora of Colorado and the Rocky Mountains. He worked on the faculty of Colorado State University (CSU) and collected over 10,000 botanical specimens from across the state.

Key takeaways

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

Reference excerpt

Harold David Harrington (March 14, 1903 – January 22, 1981) was an American botanist who specialized in flora of Colorado and the Rocky Mountains. He worked on the faculty of Colorado State University (CSU) and collected over 10,000 botanical specimens from across the state. His 1954 book, Manual of the Plants of Colorado, was the first comprehensive flora of Colorado in nearly 50 years and remains an authoritative work. With his wife and fellow botanist Edith, he traveled around the United States, Europe, and Pacific, bringing back botanical photographs for use in teaching. He published 17 books while at CSU, where the majority of his collection of specimens are kept as part of the university's herbarium that he had previously curated. He is the namesake of two species of flowering plants endemic to Colorado: Oenothera harringtonii and Penstemon harringtonii.

Early life and education Harold David Harrington was born on March 14, 1903, in De Motte, Indiana. He moved with his family from De Motte to Mitchell, South Dakota, in 1909 and then to Graettinger, Iowa, in 1911. Harrington would remain in Graettinger for most of his childhood, growing up on a farm there with seven siblings. Due to financial strains spurred by the Great Depression, Harold and his older brother Elbert alternated years in college so that one could work while the other was in school. Harrington completed two years of college before returning to Graettinger as a high school teacher. He would also coach the school's basketball and football teams. Harrington completed his B.A. in biology in 1927 at Iowa State Teachers College. At the University of Northern Iowa, Harrington completed his M.S. in 1931 and Ph.D. in 1933, both in botany. The same year of his doctorate, he married fellow botanist Edith Jirsa in Waterloo, Iowa.

Career Harold Harrington accepted a position at the Colorado Agricultural College (now Colorado State University) in Fort Collins, Colorado, where he taught taxonomy. He worked as assistant to Ernest Charles Smith, the curator of the college's herbarium. Harrington then taught at the Chicago Teachers College (now Chicago State University) before returning to Colorado A&M in 1943 to become the curator of its herbarium – a position he would hold for 25 years – and a professor of botany. Whereas his mentor Smith had been concerned primarily with collecting willow specimens, Harrington eventually contributed approximately 6,200 specimens to CSU's herbarium. While he did not collect to describe new species, he would identify unusual examples and submit them to the relevant experts. One such collection, made in June 1951, resulted the identification of a new Penstemon species, which was named for him. Other collections were submitted to him from various people – including, according to his obituary in the Colorado Native Plant Society Newsletter, "extension agents, farmers, ranchers, [and] elementary school pupils" – for whom Harrington sought to identify their collections. In 1954, Harrington's Manual of the Plants of Colorado was published after years of research. The production of such a flora had been the reason Harrington was brought to Colorado in 1943. This was the first comprehensive account of the state's flora of since the 1906 Flora of Colorado by Per Axel Rydberg. Harrington's book remains an authoritative text on Colorado's flora and one in 30 of its entries were the first time a plant was recorded in the state. In order to make the text affordable to students, the book was self-published. Edith, who aided in collecting specimens and preparing her husband's publications, hand-typed the 1954 book and called it her "small way" of helping. Harrington ultimately published 17 books while working at CSU. These included collaborations with the Japanese illustrator Y. Matsumura on the 1955 The True Aquatic Vascular Plants of Colorado and 1967 Edible Native Plants. The Harringtons also traveled, visiting Europe in 1964 and taking photographs of various plants for educational use back on the Front Range. Their travels led them to visit every state in the continental U.S. The botanist William Alfred Weber wrote that Harrington "was a large person, very quiet and even-tempered, not terribly outgoing, but someone one could be comfortable with". During trips to collect specimens with students, he would play the ukulele at the campfire after the day's work. He could also play the Spanish guitar and violin, the latter of which he had taught himself to play while in college and had played to supplement his income while in school. Harrington was also a poet and included one of his poems in the introduction to his final book.

Later life and death In 1968, Harrington retired as professor emeritus. He continued writing on botany, publishing Western Edible Wild Plants in 1972 and his final work, How to Identify Grasses and Grasslike Plants, in 1977. He and his wife performed a final round trip through the Colorado Rockies during the summer of 1980. The same year, the couple visited a variety of Pacific islands, including Hawai'i, and Australia. Harold Harrington died on January 22, 1981.

Worked examples

Example 1 — a first encounter with Harold Harrington

Start with the simplest possible case. Write down what Harold Harrington 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 Harold Harrington 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 Harrington 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 Harrington

In research
Harold Harrington 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 Harold Harrington 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 Harrington is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1903 births, 1981 deaths, 20th-century American botanists, so understanding it makes those chapters shorter.
In everyday life
Look for Harold Harrington 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.
