On January 15, 1972, Leonid Pliouchtch, a Ukrainian mathematician who was unknown at the time, was locked up in a Soviet psychiatric institution and accused of dissidence. His wife, Tatiana, fought for his defense and contacted a committee of French mathematicians to help him. Led by Laurent Schwartz, they launched a three-year campaign to secure his release and succeeded in getting the USSR to back down on the issue.
