Dear Joshs

Jane and I are happy that you will stay with us. If you should
become obnoxious, we will pack you off to a hotel.

Regarding the lecture, I suggest that you plan a popular lecture
for Friday and a more advanced talk for ionday. The audience for your
Friday talk will probably be between fifty and two hundred. A sub—
stantial fraction will be people with only a slight knowledge of
microbiology. I think that it would be very nice if you could present
your whole story for sexual reproduction in coli. You need not refer
to radiation in any way or even make the lendBplications that Luria
would surely employ. I think it would be very nice if you would Come
bring oyt the fundamental, importance of recombination for genetics ro"

I Aah epee cae patent would only modify what I have said by 4 7 a
telling you that you have a free hand to discuss whatever you like. Akasa y

My plans are to leave Chicago late Thursday afternoon, spend the -

night in Lafayette, and proceed to Crawfordsville in the morning. T+ _3e

It is the only way I can get there in time. Anyway, there are some : A eel
friends at Purdue that I want to see, whl mothe

Let me tell you how you can reach us when you arrive. Our ‘
address is 1125 East 61st Street; phone Midway 3-1959. Jane is at

‘Midway 3-0300, Extension 1170, until 5:00, and then goes home and

is there all evening. By the way, to spare your nickels, the lab

phone during the day is Butterfield 8-800, Extension 61. After

5:00, it is Butterfield 8-809 or 805. Szilard's home address is
816 Blackstone; phone Midway 3-055.

I am sorry I won't be at the dinner, but I am sure that Szilard
will take good care of you. We are trying to get tickets for a
decent play. Alternatively, there is a documentary film exhibition
that evening. It will be good to see you both.

Sincerely,

(ukick Idol?)
