John Campbell Merriam

John Campbell Merriam 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 John Campbell Merriam rather than just read about it. In short: John Campbell Merriam (October 20, 1869 – October 30, 1945) was an American paleontologist, educator, and conservationist. The first vertebrate paleontologist on the West Coast of the United States, he is best known for his taxonomy of vertebrate fossils at the La Brea Tar Pits in Los Angeles, particularly with the genus Smilodon, more commonly known as the sabertooth cat.

Key takeaways

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

Reference excerpt

John Campbell Merriam (October 20, 1869 – October 30, 1945) was an American paleontologist, educator, and conservationist. The first vertebrate paleontologist on the West Coast of the United States, he is best known for his taxonomy of vertebrate fossils at the La Brea Tar Pits in Los Angeles, particularly with the genus Smilodon, more commonly known as the sabertooth cat. He is also known for his work to extend the reach of the National Park Service.

Biography He was born in Hopkinton, Iowa, the eldest child of postmaster, store proprietor, and American Civil War veteran Charles E. Merriam. His middle name Campbell was his mother's middle name, and the maiden name of his maternal grandmother. Both his father Charles E. Merriam and his paternal uncle Henry C. Merriam had served as officers in the 12th Iowa Infantry, Company K; after capture at the Battle of Shiloh, they were sent to Libby Prison for some time before being returned to the battlefields. Eventually, when the two brothers were mustered out, they returned to Iowa, married, and raised families. As a young man, he began collecting Paleozoic invertebrate fossils near his Iowa home. He received a bachelor's degree from Lenox College in Hopkinton, Iowa, his father's alma mater, then went to the University of California to study geology and botany under Joseph Le Conte. He later went to the Ludwig-Maximilians-Universität München in Germany to study under the famous paleontologist Karl von Zittel. In 1894, he returned to the U.S. and joined the faculty at the University of California, teaching and performing research in both vertebrate and invertebrate paleontology. In 1901, one of his lectures on paleontology inspired the young Annie Montague Alexander, who financed and took part in his expedition that year to Fossil Lake in Oregon. Alexander, who went on to a lifelong career as a paleontological benefactress, financed his subsequent expeditions to Mount Shasta in 1902 and 1903, as well as his famous 1905 Saurian Expedition to the West Humboldt Range in Nevada. During this expedition Merriam unearthed 25 specimens of ichthyosaur, many of them considered the finest ever found. In 1903, he was recognized as an Associate Member of the Boone and Crockett Club, a wildlife conservation organization founded in 1887 by Theodore Roosevelt and George Bird Grinnell. In 1912, he was appointed chairman of the Department of Paleontology at the University of California. That same year he began his famous studies of vertebrates at the La Brea Tar Pits. He and his students categorized many of the vertebrate fossils found at the site, and many more were placed in storage. The smilodon was later established as the California state fossil. In 1914, Merriam was elected to the American Philosophical Society. In 1918, he was elected to the United States National Academy of Sciences. That same year, he co-founded the Save the Redwoods League, which began significant preservation efforts after Merriam traveled the Redwood areas of Humboldt County, California in 1922 seeking to spare its old-growth the effects of logging he witnessed in Redwood forests closer to San Francisco. A biography, which details his efforts to preserve wild lands in California and throughout the United States, was published in 2005. In 1919, Merriam served as president of the Geological Society of America. In 1920, he was appointed Dean of Faculty at the University of California, Berkeley, but he left that same year to become president of the Carnegie Institution in Washington, D.C. His departure caused the university to combine the Paleontology Department with the Geology Department, angering Merriam's benefactress, Annie Alexander, who subsequently founded and endowed the university's Museum of Paleontology. As the head of Carnegie Institution, Merriam's administrative duties led to a reduction in his research for the rest of his career. He accomplishments as president included helping to advance the educational programs of the National Park Service, as well as helping to preserve the California redwoods. He was elected to the American Academy of Arts and Sciences in 1921. His published papers are collected in a four-volume set published in 1938 by the Carnegie Institution. Merriam was a founding member of the Galton Institute and a cautious political supporter of eugenics. Notably, his paternal first cousin Frank Merriam, the eldest child of Civil War veteran Henry C. Merriam, served as the 28th Governor of California between 1934 and 1939.

Worked examples

Example 1 — a first encounter with John Campbell Merriam

Start with the simplest possible case. Write down what John Campbell Merriam 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 John Campbell Merriam 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 John Campbell Merriam 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 John Campbell Merriam

In research
John Campbell Merriam 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 John Campbell Merriam 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
John Campbell Merriam is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1869 births, 1945 deaths, 19th-century American archaeologists, so understanding it makes those chapters shorter.
In everyday life
Look for John Campbell Merriam 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.
