The U.S. Postal Service on March 8 unveiled a stamp honoring researcher Jonas Salk at Pitt’s Salk Hall, the site where Salk and his fellow researchers developed the killed-virus polio vaccine in the early 1950s.

Canadian artist Mark Summers created the Salk portrait based on a 1954 photograph taken in Pitt’s Virus Research Laboratory.

The 63-cent stamp is part of the postal service’s distinguished Americans series, which features Albert Sabin, Joseph W. Stilwell, Claude Pepper, Hattie W. Caraway, Edna Ferber and Wilma Rudolph.
