Mersenne and Gassendi
It is commonly believed—on the authority of many textbooks—that Gassendi (1592—1655) was the first to measure the velocity of sound in air. The evidence for this belief is examined and found to be insufficient. It is suggested that the first measurements were made by Mersenne (1588—1648). Gassendi knew of this work and referred to it inhis writings but did not make any experiments himself. The various values for the velocity of sound attributed to Mersenne by subsequent authorities are shown to be all derived from his original value of 230 toises per second, using different units or different conversion factors.
