[1] In 1888 he was awarded his doctorate in natural science with the continuation of research commenced by Victor Meyer on the molecular weight of substances at high temperatures.

In 1897 he became a professor of the Department of Inorganic Chemistry at the University of Kiel where he continued his research on the determination of vapour density.

After the war he increased his research activities considerably, often in close co-operation with his younger brother Wilhelm Biltz who was also professor of chemistry and with other highly renowned chemists.

[1] The German Chemical Industry established in 1925 the Heinrich Biltz Foundation which was destined to support highly skilled students.

In honour of the merits of Heinrich Biltz, Walter Hückel issued an obituary in the journal Chemische Berichte and annexed a complete bibliography of his work.
