Sir Herman David Weber FRCP[1] (30 December 1823 – 11 November 1918) was a German physician who practiced medicine in England.

Weber attended Gymnasium in Fulda in 1838, but started his medical studies at Marburg University in 1844, graduating from Bonn in 1848.

About 1854, he attended Guy's Hospital in London and became a member of the College of Physicians in England in 1855; he was elected a fellow in 1859.

For many years, he served as the house physician (aka resident medical officer) at London's German Hospital.

Based on his pioneering work on open-air treatment of consumption, he was knighted by Queen Victoria in 1899.
