Hamnet Holditch

Rev. Hamnet Holditch, also spelled Hamnett Holditch (1800 – 12 December 1867), was an English mathematician who was president of Gonville and Caius College, Cambridge.

In 1858, he introduced the result in geometry now known as Holditch's theorem.

Hamnet Holditch was born in 1800 at Lynn, Norfolk. In 1818, he began his studies of mathematics at the University of Cambridge (Caius College), having obtained his bachelor's degree (B.A.) in 1822 and his master's degree (M.A.) in 1825. He was Senior Wrangler in the Tripos and was awarded the Smith's Prize of 1822. He was a Fellow of Caius College, and its President from 1835 until 1867, when he died.^[1]

He was the only son of George Holditch, and had two sisters.
