Walter Hieber (18 December 1895 – 29 November 1976) was an inorganic chemist, known as the father of metal carbonyl chemistry.
In 1935 he was appointed Director of the Inorganic Chemical Institute at the Technical University in Münich.
Among his numerous research findings, Hieber prepared the first metal carbonyl hydrides such as H2Fe(CO)4 and HMn(CO)5.
Hieber was highly decorated for his work, including in 1951 the Alfred Stock Prize.
One of his most famous students was Nobel prize winner Ernst Otto Fischer.
