Query: On the prehistory of growth of groups   The subject of growth of groups has been active in the former Soviet Union
since the early 50's and in the West since 1968, when articles of \v{S}varc and
Milnor have been published, independently. The purpose of this note is to quote
a few articles showing that, before 1968 and at least retrospectively, growth
has already played some role in various subjects.
