Othniel Charles Marsh

Othniel Charles Marsh 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 Othniel Charles Marsh rather than just read about it. In short: Othniel Charles Marsh (October 29, 1831 – March 18, 1899) was an American professor of paleontology. A prolific fossil collector, Marsh was one of the preeminent paleontologists of the nineteenth century.

Key takeaways

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

Reference excerpt

Othniel Charles Marsh (October 29, 1831 – March 18, 1899) was an American professor of paleontology. A prolific fossil collector, Marsh was one of the preeminent paleontologists of the nineteenth century. Among his legacies are the discovery or description of dozens of new species—including Stegosaurus and Triceratops—and theories on the origins of birds. He spent his academic career at Yale College and was president of the National Academy of Sciences. Born into a modest family, Marsh was able to afford higher education thanks to the generosity of his wealthy uncle George Peabody. After graduating from Yale College in 1860 he traveled the world, studying anatomy, mineralogy and geology. He obtained a teaching position at Yale upon his return. From the 1870s to 1890s, he competed with rival paleontologist Edward Drinker Cope in a period of frenzied Western American expeditions known as the Bone Wars. Marsh's greatest legacy is the collection of Mesozoic reptiles, Cretaceous birds, and Mesozoic and Tertiary mammals that now constitute the backbone of the collections of Yale's Peabody Museum of Natural History and the Smithsonian Institution. Marsh has been called "both a superb paleontologist and the greatest proponent of Darwinism in nineteenth-century America."

Biography

Early life and family Othniel Charles Marsh was born on October 29, 1831, near Lockport, New York. He was the third of four children born to Mary Gaines Peabody (1807–1834) and Caleb Marsh (1800–1865). The Marsh (nee Marshe) family and Peabody families immigrated to America from England in the 1630s. Mary died shortly after the birth of her fourth child in 1834. Caleb remarried in 1836 and Othniel moved with the family to Bradford, Massachusetts. Soon after, Caleb's business fortunes soured, and Othniel's early years were marked by financial struggles. Caleb purchased a farm in Lockport when Marsh was twelve. As the eldest son, Othniel was expected to assist his father on the farm, and the two had a contentious relationship. Othniel much preferred excursions in the woods to his chores. Among his childhood influences was Ezekiel Jewett, a former military officer and amateur scientist who fostered Othniel's interest in the sciences. Jewett had been drawn to the area by the fossils unearthed by the enlargement of the Erie Canal, and the two would hunt and prospect for specimens together. By 1847, Othniel was attending school at the Wilson Collegiate Institute, and later attended the Lockport Union School. Othniel was undecided as to what he would do for a living, but his future was dramatically changed due to the intervention of his uncle George Peabody, a successful banker. With Peabody's financial assistance (spurred by Marsh's aunt, Judith), Marsh enrolled in Phillips Academy in 1851. Older than most of the other students, he was nicknamed "Daddy" by his peers. He was initially an unremarkable student, devoting much of his time to leisure and games, but the next year decided to focus on his studies. "I changed my mind," he later told a biographer, "during an afternoon spent on Dracut Heights [Lowell]. I resolved that I would return to Andover, take hold, and really study." Marsh applied himself to his studies and graduated valedictorian of his class in 1856. In the summers off of school, he prospected for minerals in New York, Massachusetts and Nova Scotia. Upon graduation, Marsh decided to attend Yale, rather than Harvard, where many of his relatives had attended. He ran his letter to George Peabody asking for the funds by Judith first, who disapprovingly noted it contained two spelling errors. Peabody agreed to cover Marsh's expenses and give him an allowance for spending money, and Marsh moved to New Haven in September. Marsh was a good student, but not a thrifty one; Judith, who was in charge of monitoring Marsh while Peabody was in Europe, regularly upbraided her nephew for his lax accounting habits and large expenses. Marsh graduated eighth in his class, using a scholarship he won for the best examination in Greek to finance a master's degree from Yale's Sheffield Scientific School, as he developed an interest in becoming a professor of science. While in graduate school, Marsh published his first scientific papers on minerals and vertebrate fossils from his Nova Scotia trips, which possibly inspired Marsh's interest in vertebrate paleontology. He obtained his master's degree in 1862.

Worked examples

Example 1 — a first encounter with Othniel Charles Marsh

Start with the simplest possible case. Write down what Othniel Charles Marsh 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 Othniel Charles Marsh 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 Othniel Charles Marsh 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 Othniel Charles Marsh

In research
Othniel Charles Marsh 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 Othniel Charles Marsh 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
Othniel Charles Marsh is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1831 births, 1899 deaths, 19th-century American geologists, so understanding it makes those chapters shorter.
In everyday life
Look for Othniel Charles Marsh 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.
