In this letter, Anfinsen congratulated Leder on obtaining a patent for one of his developments, a genetically modified mouse
known alternatively as the "Harvard Mouse," or "Oncomouse." The patent is held by the DuPont Corporation,
which funded Leder's work at Harvard.
Dick Nichols sent me a copy of the Times story on your patent. Having seen the little beasts in your lab on my last visit,
it was no surprise, but the fact that the patent was issued, was. It seems like a very reasonable and important thing for
the Patent Office to have done.
I just want to wish you the very best of luck with the next stages of your work. I might ask you one favor: should you ever
get around to humans, those of us who live in Baltimore would be very grateful if you could do something about developing
individuals that could bolster our local Oriole baseball team and get it out of the cellar.
