(The following brief sketches fill out the last nine of the 23 candidates on the Corporation's latest list of men still being considered for the Harvard presidency.

None of the biographies are intended as a complete history of qualifications; rather they are an attempt to show what kind of man each person is, according to comments from students and faculty members at Harvard and the man's own university.)

Matthew Meselson, 40, Harvard professor of Biology:

A quiet man, Meselson is highly-respected within his field and has managed to avoid making enemies by steering clear of Faculty polities. One of his greatest assets-is his youth.

Colleagues describe Meselson as a hard person to get to know, but he is well-liked both by Faculty and students. He is an extremely diplomatic person, perhaps because of the nature of his work.

Meselson, who began his career as a research fellow at Cal Tech, has long been associated with the government's development of chemical and biological warfare. Throughout the association, Meselson has been a strong opponent of the employment of nerve gas.

Diplomacy comes into light because Meselson must work closely with the very people he is trying to undo in Washington; that he has accomplished as much as he has in limiting chemical and biological warfare is something of a miracle.

At present, Meselson is conducting a study of nerve gas for the American Association of University Professors.

Meselson is not a Harvard graduate; he received a Ph. D. from the University of Chicago in 1931 and later took a Ph. D. from Cal Tech. He joined the Harvard Faculty in 1960, and was appointed professor of Biology in 1964.

Wolfgang K. H. Panofsky, 51, director of Stanford Linear Accelerator Center:

Born in Berlin in 1919, Panofsky came to the United States in 1934 and became a naturalized citizen. He has no previous connection with Harvard, having taken his undergraduate degree from Princeton in 1938 and his Ph. D. from Cal Tech in 1942.

Panofsky is renowned as a brilliant experimental physicist; he has done most of his work on linear acceleration and he conceived the idea of the two-mile accelerator at Stanford.

The son of art historian Irwin Panofsky, Panofsky and his brother, Hans, graduated number one and two from Princeton.

During the height of the McCarthy era in 1952, Panofsky resigned his position on the Berkeley faculty when he was asked to sign a loyalty oath. He has been at Stanford ever since.

Panofsky staunchly opposed the ABM system while it was being debated in the Senate in 1969, and he was asked to testify before the Senate Sub-Committee investigating the system.
