Executive summary: Idempotent and nilpotent

Benjamin Peirce was mentored from childhood by Nathaniel Bowditch, and became one of the most respected mathematicians and astronomers of the 19th century. He was a faculty member at Harvard for nearly fifty years, during which time the school evolved from a regional college into an institute of national stature, in no small part due to Peirce. He coined the algebraic terms idempotent and nilpotent, and his mathematical works included a paper establishing that no odd perfect number could have fewer than four prime factors.

He co-founded the National Academy of Sciences, Harvard's Lawrence Scientific School, and the Harvard College Observatory. He then lobbied Harvard's administration for purchase of a bigger, better telescope which, when installed, was used to discover Neptune in 1846. He used mathematical calculations to accurately predict the paths of comets, phases of the moon, Neptune's orbit, and that planet's effect on the orbit of Uranus and on the other planets. During a three-year stint as Superintendent of the US Coast Survey, he oversaw production of a map of the United States, and organized expeditions to Alaska, the Chatham Islands, Nagasaki, and Sicily.

Peirce was briefly teased in a poem by classmate Oliver Wendell Holmes as "That boy with the grave mathematical look / made believe he had written a wonderful book". Peirce's brother-in-law was US Senator Henry Cabot Lodge.
