Der rrofessor Lederberg:

MP. ase u, Genesin,) wno recently wrote you concerning
the possibility. Oming to work in your deosurtment, h«s

requested me to send you a letter of recommend:tion. It is
a pleasure for me to ao so, for wr. Ganesan not only
possesses outstanding scientific ability but is -lso
endowea with a fine chsracter and an attractive personality.
He spent two yesrs in Bangalore «.t the Indi=n Institute
of Science where he succeeded, under difficult conditions,
in working out a very satisf-ctory methoa for staining
yeast nuclei. Later he obtained a position with Dr. Swemi-
n-thun at the Indian agricultural research Institute in
New Delhi where he curried out work on embryo culture of
jute as well as assisting in a lerge scale project on the
cytogenetics of whest. weanwhile, on his own time, he
continued his studies in ‘yeast cytology in order to perfect
his stcining technigue. ‘Through the efforts of Professor
Winge he obtained a Danish fellowship, nd he hss been
working at the Carlsberg Laboratorium since September 1957.
Here he h-s been chiefly occupied with cytologic2l investi-
gations, in particulsr with a compsrstive study of heploid
and Giploia cells of Sacch:=romycesy which is now being
prepured for oublication. His cytological preparations. are
of u high degree of excellence, and I h=ve never seen any
which surpass them. Recently he commenced work on a probtem
dealing with the genetics of melibiose fermentation «nd st
present is pursuing it with his customary energy snd interest.
since tine Indian government appears to be interested in
having Mr. Ganesan obtain his doctorate unuaer your direction,
and Sinee ne wus been sxssured of 3 position in Dr. Swami-
n-than's aepurtment upon his return from .merica, I hope
thst this plan can be realized. If, for my pxrt, can give
him an unqualified recommendation.

With best regsurds,

Yours sincerely,
Gtleme Kebety
