Jacobus Henricus (Henry) van 't Hoff (1852-1911) was a chemist credited with founding the science of stereochemistry, and in 1901 he was awarded the first Nobel Prize in chemistry. The majority of the papers are those reflecting family affairs or honors accorded van 't Hoff for his work. This collection does not contain his scientific or working papers except for notes of two lectures and copies of his published papers. The papers are mostly in Dutch. The papers span from 1837 to 1924.
