For 40 consecutive years, from 1967 to 2006, the Law School surveyed its alumni regarding their lives and careers. The project began in 1967 with the mailing of a questionnaire to the class of 1952 shortly before their 15th reunion. The results proved interesting enough that surveys were sent each year thereafter to the class 15 years out. In 1973, the classes 5 years out were added to the survey.
