Heinrich Friedrich Wilhelm Braun (1 January 1862 – 26 April 1934) was a German surgeon remembered for his work in the field of anaesthesiology.
The following year he was appointed chief surgeon and medical director of the Royal Saxonian Hospital in Zwickau, a position he maintained until his retirement in 1923.
Braun made important contributions in the development of general, local and regional anaesthesia.
In 1901 he devised an apparatus for mixed-gas anaesthesia, and in 1903 recommended the addition of adrenaline as a vasoconstrictor to local anaesthetics.
In 1905 he introduced procaine into clinical medicine, an anaesthetic that had previously been synthesized by Alfred Einhorn (1856-1917).
