Where was the first conference of the Pugwash Conferences on Science and World Affairs held in the year 1957?

The first Pugwash Conference on Science and World Affairs took place in July 1957 in the village of Pugwash, Nova Scotia, at Cyrus Eaton’s summer home known as Thinkers’ Lodge. Contemporary histories and the Pugwash organization’s accounts identify the meeting of twenty-two scientists convened there in response to the Russell–Einstein Manifesto, with Eaton financing and hosting the gathering that gave the movement its name [2]. The site is now recognized as the birthplace of the Pugwash movement and a Canadian National Historic Site, explicitly citing the 1957 conference at Thinkers’ Lodge as the seminal event.
