Early life

A member of the scientifically inclined LeConte family, John Lawrence was born in New York City, the son of naturalist John Eatton Le Conte. His mother, Mary A. H. Lawrence, died when John Lawrence was only a few months old, and he was raised by his father.<ref name=evans/> Most reliable sources spell his name "LeConte" or "Leconte", without the space used by his father, and samples of his signature show the preference for "LeConte".

He graduated from Mount Saint Mary College, Emmittsburg, Maryland, in 1842, and from the College of Physicians and Surgeons, New York, in 1846. He worked as a chemical assistant to John Torrey and after receiving his medical degree he briefly practiced medicine. He also married Helen Grier and in the same year he gave up medical practice. During the civil war he again worked as a medical inspector and received the rank of lieutenant colonel. Having inherited enough money to make himself independent, LeConte did not practice medicine professionally.<ref name=FV/> Influences in his life included Louis Agassiz and Hermann Rudolph Schaum who stayed in the Leconte home.<ref>Template:Cite journal</ref>

While still in medical college, in 1844, John Lawrence traveled with his cousin Joseph LeConte to the Great Lakes. Starting at Niagara Falls, they visited Detroit and Chicago and traversed Michigan, Wisconsin, Iowa and Illinois before returning up the Ohio River to Pittsburgh and on to New York.<ref name=FV>Template:Cite journal</ref> John Lawrence published his first three papers on beetles that year.<ref name=evans/>

Travels

After graduating from medical college John Lawrence LeConte made several trips west, including to California via Panama in 1849. While in San Francisco, he sent 10,000 beetles preserved in ethanol back to his father. Another 20,000 beetle specimens were lost in a fire in 1852.<ref name=evans/> LeConte also traveled to Europe, Egypt and Algiers.<ref>Template:Cite journal</ref> He spent two years exploring the Colorado River, and was in Honduras for the building of the Honduras Interoceanic Railway, and in Colorado and New Mexico with the party surveying for the Kansas Pacific Railroad.<ref>Template:Cite book</ref> He moved to Philadelphia in 1852, residing there for the rest of his life. He died in Philadelphia on November 15, 1883.<ref>Template:Cite news</ref>

Military service

During the American Civil War he enlisted in the Army Medical Corps as a surgeon. He was promoted to the position of medical inspector and reached the rank of lieutenant colonel by the end of the war.Template:SfnTemplate:Sfn

U.S. Mint

In 1878 he became the chief clerk (assistant director) of the United States Mint in Philadelphia. He retained that position until his death in 1883.<ref name=evans/>

Scientific societies

LeConte was active in the scientific societies of his time, with stints as vice-president of the American Philosophical Society (1880–1883) and president of the American Association for the Advancement of Science (1873). He was a founder of the American Entomological Society, and a charter member of the National Academy of Sciences.<ref>Incorporators of the NAS</ref>

LeConte communicated with and collected birds and other natural history specimens for Spencer Fullerton Baird, a distant cousin and assistant director and then director of the Smithsonian Institution for a total of 39 years. In turn Baird asked other naturalists to collect beetles for LeConte.<ref name=birdname/>

In the 1850s, LeConte collected some crystals from a cave in Honduras being mined for bat guano. It was later found to be a new mineral that was named "lecontite" in his honor.<ref>Template:Cite journal</ref>
