Herbert McLeod

Herbert McLeod ( born February 19, 1841 in Stoke Newington, † October 1, 1923 ) was a British chemist. According to him, the McLeod vacuum gauge, a device for measuring small pressures was named.

McLeod studied chemistry at August Wilhelm von Hofmann at the Royal College of Chemistry. In 1865 he became assistant to Edward Frankland in 1871 until he was appointed as professor at the Royal Indian Engineering College ( RIEC ) at Cooper's Hill, near London.

McLeod's diary, which he led from 1860 to 1923, is primarily a list of social events without personal views and thus a reliable historical source for the scientific life in Victorian London.

From 1881 he was a Fellow of the Royal Society.
