Ernst Otto Beckmann (1853-1923) 生于德国索伦根,在莱比锡大学学习化学和药学。除了Beckmann反应,他还发明了Beckmann温度计,是一种可准确到0.001℃的示差温度计,可用于通过凝固点法和沸点法测量分子量。

1. Beckmann, E. Chem. Ber. 1886, 89, 988. Ernst Otto Beckmann (1853-1923) was born in Solingen, Germany. He studied chemistry and pharmacy at Leipzig. In addition to the Beckmann rearrangement of oximes to amides, his name is associated with the Beckmann thermometer, used to measure freezing and boiling point depressions to determine molecular weights.
