Dear Don:

Concerning CHARLES YANOFSKY and his qualifica-
tions as an outstanding scientist:

his talents and accomplishments are so well
known to both of us and to our mutual colleagues
that it is very much a formality for me to be
describing them to you. His work on the linear
order of mutational changes in an enzyme protein
corresponding to linear order of Sites in a gene
is one of the most Significant contributions in
recent years to both genetics and biochemistry.
Besides the classic elegance of the underlying
concept, its execution in the laboratory was a
success of experimental finesse and hard work
which has few parallels in scientific history.
Although he is very well known and recognized
among his seientific colleagues, he has been too
modest to seek or encourage public acclaim, but
I have no doubt that the beauty of his ‘work will
come to be very widely recognized as an outstanding
example of the best fruits of the convergence
of genetics and chemistry.

yf A N5 f0ely &

Sincerely
