Hermann Blau (born January 21, 1871 in Graben near Karlsruhe , † February 18, 1944 in Stephanskirchen near Rosenheim ) was a German chemist and inventor who had success at the beginning of the 20th century with a safer version of the city ​​gas shipped in steel bottles . It was named blue gas after him and was the first liquid gas.

Blau himself was a pharmacist and studied with Adolf von Baeyer . In 1903 he received a patent on blue gas and in 1904 founded a factory in Augsburg-Oberhausen. He was successful with these forerunners of the propane gas cylinders until the 1920s, they were used for heating, lighting and cooking, for example for lighthouses and had advantages wherever gas pipes were not laid. They were later replaced by propane and electricity, but blue gas made a name for itself again as a fuel for zeppelins in the 1930s.
