From the article by R. Evans and J. R. Henderson in J. Phys.: Condens. Matter 21 (2009) 474220 Ode to Richard Palmer and other travellers on the imaginary axis
But, be careful ... David Goodstein wrote in the book States of Matter, 1975, Dover N.Y. "Ludwig Boltzmann, who spent much of his life studying statistical mechanics, died in 1906, by his own hand. Paul Ehrenfest, carrying on the work, died similarly in 1933. Now it is our turn to study statistical mechanics. Perhaps it will be wise to approach the subject cautiously" ...
