Peirce was home-schooled by his father, Benjamin Peirce, a Harvard professor and the nation's leading mathematician. Benjamin especially taught Charles how to solve increasingly complex math and logic problems.  He graduated from Harvard College in 1859 with mediocre grades; he later earned degrees in chemistry and biology with distinction.  He became a research scientist with the United States Coast Survey, 1861-1891, doing research on gravity. At the same time he taught and did research at Harvard in logic and astronomy.

Peirce described himself when a senior at college as being vain, snobbish, uncivil, reckless, lazy, and ill-tempered. He suffered from an early age from trigeminal or "facial" neuralgia, an extremely painful condition. Lazy he was not, but the other personality traits did not help his cause in seeking a permanent faculty appointment anywhere, a cause defeated by his opponents' reporting to potential academic employers the fact of his having lived with his future second wife Juliette while still married to his first. He inherited some money in 1887 and took his books and wife Juliette to what he called "the wildest county of the Northern States", near Milford, Pennsylvania, an area which attracted him because it was a watering hole for captains of industry<ref>See "Discovering the American Aristotle" by Edward T.

There he built a house which he called Arisbe, where he hoped to have intellectual guests regularly from New York City, and which he and Juliette continued to expand even during the poverty from which they never finally escaped.
