After several years working in the Freshman Dean's Office, he became assistant director of admissions in 1964.

In 1972, Jewett was appointed dean of admissions and financial aid. During his 13 years in the post, he implemented the current needblind admissions policy, which requires the admissions committee to evaluate applicants without reference to their ability to pay tuition.

During his tenure as dean of the College, much of Jewett's time was spent on two issues: advising and housing. Although he often stated his personal preference for randomization, Jewett helped forge the non-ordered choice compromise which governs the housing lottery.

In a recent interviews, he said he was proudest of his work to plan major renovations on campus, including reconstruction of the Yard dorms and the makeover of Memorial Hall into a student center which will be completed next year.

"I feel we will have made real progress in improving the physical environment for undergraduates," Jewett said.

The dean said he plans to remain at Harvard in a capacity that leaves him time to pursue "personal interests." He has also said he'd like to travel to Australia, New Zealand or Africa and to spend more time at his Maine vacation home.
