My dear Dr. Nirenberg
I should like to compile a collection of autographs of prominent persons.
I hope you do not mind my imposing upon you and will permit me to include you to include you in my collection as I sincerely believe that you, through your inspiring efforts and outstanding contributions, are endearing yourself to many people.
If you would be so kind as to autograph the enclosed card, I shall be very grateful. A stamped, return envelope is included for your convenience.
If you have a photograph available that you could autograph, it would please me immensely.
I would be interested in knowing, Dr. Nirenberg, what you consider your greatest satisfaction thus far during your career.
With cordial best wishes, Sir, for continued success and much happiness,
Respectfully yours,
Roger Harris
