1812–1851
A 19th-century mathematician with a gift for rigorous geometry, he wrote dense but ambitious studies of conic sections and partial differential equations while teaching at the Royal Military College, Sandhurst.

by George Whitehead Hearn
George Whitehead Hearn was a British mathematician who lived from 1812 to 1851. The Royal Society's Science in the Making catalog identifies him as a professor of mathematics at the Royal Military College, Sandhurst.
He is best known for Researches on Curves of the Second Order (1846), a substantial work on conic sections, cones, and spherical conics. Library and archive records also connect him with a study of partial differential equations from the same period, showing a strong interest in advanced analytical mathematics.
Not much biographical detail seems to be widely available online, but the surviving record suggests a serious specialist whose work was aimed at mathematicians rather than a general audience. His books remain accessible through major digital libraries, which has helped preserve his place in the history of 19th-century mathematical writing.
