In 1944 under the cover of Columbia University's Special Alloys and Metals Laboratory, he was asked to join the Manhattan Project.

Numerous scientists and employees from Oak Ridge Institute of Nuclear Studies attended along with several reporters and photographers.

At an ecumenical seminar held in honor of the fiftieth anniversary of Kent School (1955), Pollard was one of eight distinguished speakers giving talks on The Christian Idea of Education.

Other speakers included Princeton University historian and Presbyterian layman E. Harris Harbison, Cry, The Beloved Country author and Anglican layman Alan Paton, Professor of Liturgics and Episcopal priest Massey H. Shepherd, Roman Catholic priest John Courtney Murray, Roman Catholic layman and then professor emeritus of Princeton University Jacques Maritain, Russian Orthodox priest and then Harvard University professor Georges Florovsky, and Protestant theologian Reinhold Niebuhr.

Pollard and Edmund Fuller co-edited the results of this seminary, which were published as The Christian idea of education: papers and discussions (Yale University Press, 1958).

The most exquisite statement of what the process of education should be is not to be found amid the majestic vivacity of the humanists but in the conversational, almost casual speech by Edward Teller, the physicist.

The most acute and moving theology is contributed by the executive director of the Oak Ridge Institute of Nuclear Studies, the Rev.

Their utterances explain why it has been, of all things, the dramatic demands of science on the high-school curricula that have, after thirty-five years of stagnation, at last produced the beginnings of a new humanism in American education.
