JIAY 25, 1360 Professor Linus Pauling California Institute of Technology Pasadena, C-lifornia Dear Dr. Pauling, Upon returning from a trip to Europe, I have learned of the harasment to which you have been submitted by the Senate Internal Security Subcommittee. As one of the original signatories of your fallout at-ptement in 1957, I am proud of the fact that I helped circulate it for signatures at the University of Illinois. I only regret th t in the few days then available we collected only about 30 signatures; many more persons would have signed, I am sure, had they been approached. While I am in complete sympathy with your position with regard to %he questions asked by the Senate Subcommittee, you should feel free to use nqy name as you see fit in connection with the signing and circulating of the &tement. With kindest regards, Sincerely yours, sel/na S. E. Luria Professor of Microbiology
