OBITUARIES

Harris I. Tarlin, founder of Tarlin Scientific, died on May 7 after a long struggle with cancer. He was 65.

Born and raised in Boston, Tarlin earned a bachelor's degree in biology from Boston University and a master's degree in organic chemistry from Boston College in 1961.

Following graduation, Tarlin served two years in the U.S. Army, stationed at the Armed Forces Radiobiological Research Institute in Bethesda, Md. During his service, he was selected as a trainee in the new field of health physics, spending time at the atomic bomb test site in Nevada and at Oak Ridge National Laboratory.

Tarlin left the military to join Astra Pharmaceutical in Worcester, Mass. For 13 years he was head of Astra's analytical lab, where he was commended for his contributions to drug development. In 1986, Tarlin founded his own company, Tarlin Scientific, which imports and distributes chemical testing equipment from a U.K. manufacturer.

Tarlin was an avid follower of current events who enjoyed reading nonfiction and practicing nature photography. He was also a student of the Holocaust and attended many lectures on the subject. He and he wife were charter members of the Holocaust Museum in Washington, D.C.

Tarlin is survived by his wife, Sheila; two children; two brothers; and a sister. Joined ACS in 1962.

Tina Weeding, a research chemist retired from the Institute of Atomic & Molecular Physics, Amsterdam, died on April 21 of complications related to multiple sclerosis. She was 49.
A Colorado native, Weeding received a B.A. in chemistry in 1977 at the University of Colorado, Denver. She also completed part of her undergraduate work at the University of East Anglia, in England, during a study-abroad program.

Weeding went on to earn an M.S. and a Ph.D. from the University of Washington, Seattle. In 1985, she started a postdoctoral position at the University of Nijmegen, in the Netherlands, where she worked on the nuclear magnetic resonance of polymers in collaboration with Akzo.

In 1988, Weeding moved to the institute in Amsterdam to become group leader of the photoionization/photodissociation group. Her research interests included resonance-enhanced multiphoton ionization and analysis of complex biopolymers of plant cell walls. Weeding stayed with the institute until 1999 when her increasing disability no longer allowed her to work. Joined ACS in 1984.

Zajac
Walter Zajac Jr.,
professor emeritus of chemistry at Pennsylvania's Villanova University, died on March 3 of colon cancer at the age of 68.

Born in Central Falls, R.I., Zajac earned a B.S. from Providence College in 1955. He went on to receive an M.S. in 1957 and a Ph.D. in 1960 from Virginia Polytechnic Institute, Blacksburg.

In 1959, Zajac joined the faculty at Villanova as an assistant professor. He stayed with the university for more than 40 years, reaching associate professor in 1964 and full professor in 1972. He taught undergraduate- and graduate-level organic chemistry and also ran chemistry courses for nurses and refresher courses for corporate chemists.

As a teacher, Zajac was known for stressing ethics and critical thinking in all his classes. He was also widely recognized for his research on the chemistry of nitro compounds. His work with carbohydrates led to the discovery of a novel cleavage reaction.

Zajac took a sabbatical in 1965 to accept a position as a senior postdoctoral fellow at the University of Alberta, in British Columbia. The grandson of Polish immigrants, he was especially pleased to take part in a National Academy of Sciences exchange program in 1968 that allowed him to serve as a guest lecturer at the Polish Academy of Sciences.

Zajac gave freely of his time to participate in a variety of professional activities. From 1989 to 1990, Zajac served as chairman of the ACS Carbohydrate Chemistry Division. He also served as chairman of the graduate committee in Villanova's chemistry department for nine years.

In his spare time, Zajac was an avid sports fan who enthusiastically supported the Philadelphia Flyers. He also enjoyed his involvement in his grandchildren's athletic activities.

Zajac is survived by his wife, Mary; three sons; two daughters; and eight grandchildren. Joined ACS in 1977.
