Herbert Brereton Baker FRS CBE (25 June 1862 – 27 April 1935) was an English inorganic chemist.

[2] During this time he was elected to a Lee's Readership at Christ Church Oxford, becoming responsible for inorganic chemistry lectures at the University.

In 1912 he was appointed Professor at Imperial College, replacing Sir T. E. Thorpe as Director of the Chemistry Department; here he remained until retiring in 1932.

[3] He also claimed that complete drying has the effect of significantly raising the boiling temperature of chemicals, but reproducibility of the results could not be achieved.

In June, 1902, he was elected a Fellow of the Royal Society[9][1] and in 1923 was awarded their Davy Medal for "his researches on the complete drying of gases and liquids".
