James Greenwood and Maclyn McCarty


James Greenwood, a former Pennsylvania congressman, recently assumed the role of president of the Biotechnology Industry Organization.

Greenwood replaces Carl Feldbaum, who served as president of BIO since its inception in 1993. Feldbaum has retired, said BIO.

Before joining BIO, Greenwood served as chairman of the Energy and Commerce Committee SubCommittee on Oversight and Investigation in the US House of Representatives. Prior to his time in congress, Greenwood served in the Pennsylvania General Assembly and in the Pennsylvania Senate. Greenwood holds a BA in social work from Dickinson College.

Maclyn McCarty, who co-discovered that genes consist of DNA, died on Jan. 2, Rockefeller University said last week.

Together with Oswald Avery and Colin MacLeod, McCarty showed in the 1940s that DNA, not proteins, carry genetic information. He held an undergraduate degree in biochemistry from Stanford University and a medical degree from Johns Hopkins University.

McCarty, who worked at Rockefeller for more than 60 years, received a Special Achievement in Medical Science award from the Lasker Foundation in 1994. He was 93.
