Sorry for only finding the GM list, here it is on the1957 IM List :

W. LOMBARDY, the same year as Fischer, R.J.

Phil


THX a lot! could you please add Lombady to the list?

Did anyone answer this?

There were 4 players 1960 for International Grandmaster:

C.E. Guimard
R. Kholmov
W. Lombardy
H.D. Rossetto

However, there is an asterisk by his name, and the footnote says: "Title
does not count for purposes of grading a tournament." My Source, Anne
Sunnucks' The Encyclopaedia of Chess - which lists all these awards year
by
year.

Cordially, Phil Innes
