•Allais did not set out to make pendulum observations during an eclipse - the 30 June 1954 eclipse fortuitously passed near Paris, and his observation was serendipitous; •Jeverdan planned to take his observations during the 1961 eclipse that was scheduled to pass near his laboratory in Bucharest; •Saxl and Allen took advantage of the solar eclipse that passed near Harvard in 1970.
