In July 1941, the Labor-Federal Security Appropriations Act, authorized the addition of chemistry, physics, and production-related courses to form an integrated ESMDT program. Funding was increased to $17.5 million ($270 million equivalent in 2008), and Dean George W. Case from the University of New Hampshire, replaced Seaton as the program director. During the next year, enrollment increased to nearly 450,000 men and women in about 7,800 courses offered by 196 colleges and universities.
