ACS honors its 50-year members in 2025

The American Chemical Society and its local sections recognize those who have reached 50 years of membership in 2025. To commemorate the 50-year milestone, ACS gives each member a 50-year certificate, a special lapel pin, and a permanent member card entitling the person to free registration at all spring, fall, and regional ACS meetings. This year, ACS has 967 50-year members worldwide; 27 chose not to have their names listed.
