I think that when it comes to the origins of the
accelerator principle the name of Mentor
Bouniatian deserves to be mentioned. From the
1920s to the very end of his life he claimed that
Aftalion had copied his work without proper
acknowledgement. This included the accelerator
principle; see e.g. the bitter words of
Bouniatian in his booklet *Mes Théories
Economiques et Albert Aftalion* (Paris, R. Pichon
& R. Durand-Auzias, 1966), p. 6.
