In 1968, Cyrus Eaton was one of the donors who made possible McMaster’s acquisition of the Bertrand Russell Archives.

In 1995, Joseph Rotblat and the Pugwash Conferences were awarded the Nobel Peace Prize "for their efforts to diminish the part played by nuclear arms in international politics and, in the longer run, to eliminate such arms,” a fitting legacy to the remarkable collaboration between Russell and Einstein forty years earlier.

Rotblat gave the Bertrand Russell Peace Lecture at McMaster in 1998 and visited the Russell Archives.

In 2008, ‘Thinkers’ Lodge,’ the primary site of the first Pugwash Conference in 1957, was designated a Canadian National Historic Site.

The 62nd Pugwash Conference was held in Astana, Kazakhstan, in 2017.
