June 1939 - A Student Council committee publishes a report attacking the requirements for the bachelor's degree. In his memoirs ("My Several Lives"), President James Bryant Conant describes the main thrust:

"The authors claimed that the concentration and distribution rules and regulations failed to ensure that an undergraduate would obtain 'an intelligible and broad view of the main areas of learning.' What they advocated was the establishment of five new introductory courses (not survey courses) - two in the natural sciences, two in the humanities and one in the social sciences - which all students should be compelled to take. In commenting on the report in my annual report for 1938-39, I stated that while I was more than a little sympathetic with the criticisms, I was still uncertain as to the details of reform. I raised the question whether 'any single program suitable for a heterogeneous group' could be devised."

June 5, 1947 - For the first time, the Harvard University Band plays in the Yard on Commencement Day.
