Yuri Krutkov

Krutkov worked on cosmology, quantum theory, statistical mechanics, tensor fields, and other areas.

Krutkov was born in St. Petersburg where his father Alexander taught Greek, Latin and Russian.

Funded by a Rockefeller Foundation grant, he worked in Germany and Holland in 1922-23 during which time he met Albert Einstein.
