Peter P. von Weymarn

Peter Petrovich von Weymarn (commonly mis-spelt von Weimarn) (July 18, 1879 – June 2, 1935) was a Russian chemist born in St. Petersburg known for his groundwork in colloid science.

In 1906 he stated the von Weymarn law: Colloidal dispersions are obtained from very dilute or very concentrated solutions but not from intermediate solutions. The relative supersaturation ratio herein is defined by S=(Q-L)/L (where Q is the amount of the dissolved material and L is its solubility).
