Ole Albert Lamm, born December 25, 1902 in Gothenburg
, died August 14, 1964 in Stockholm
, was a Swedish physical chemist whose research included diffusion
and sedimentation
phenomena.
Lamm was a graduate student under Nobel Prize laureate
The Svedberg at Uppsala University
and received his doctorate in 1937 with the thesis Measurements of concentration gradients in sedimentation and diffusion by refraction methods: Solubility properties of potato starch
. In 1945, he was appointed professor of theoretical chemistry, from 1953 physical chemistry, at the Royal Institute of Technology
in Stockholm
.
Lamm introduced the Lamm equation
which describes the concentration distribution of solutes resulting from sedimentation and diffusion under ultracentrifugation in typical sector-shaped cells.
In 1957, he was elected a member of the Royal Swedish Academy of Engineering Sciences
and in 1958, a member of the Royal Swedish Academy of Sciences
. At the occasion of his 60th birthday in 1962, a Festschrift
was published in his honour.

, was a Swedish physical chemist whose research included diffusion
Diffusion
Molecular diffusion, often called simply diffusion, is the thermal motion of all particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size of the particles...
and sedimentation
Sedimentation
Sedimentation is the tendency for particles in suspension to settle out of the fluid in which they are entrained, and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration...
