Maurice R. Barusch, 87, a retired Chevron chemist, died on July 7 of kidney cancer.

Born in Japan, Barusch grew up in San Francisco and earned his doctorate in chemistry from Stanford University in 1943. He took a job that same year at Standard Oil, which later became Chevron. Throughout his career, he developed fuel additives to improve gasoline efficiency. In 1982, he retired as vice president of Chevron Research.

In 1977, Barusch received the ACS Detroit Section's Thomas Midgley Award for his contributions to chemistry in the automotive industry.

The West Contra Costa Unified School District, in Richmond, Calif., recently honored Barusch, who worked to desegregate their schools from 1965 to 1969 as a school board member.

He is survived by his wife, Barbara Langlois; and sons, Larry and Ron. His first wife, Phyllis, died in 2003. An emeritus member, he joined ACS in 1943.

Ernst Otto Fischer, 88, a Nobel Laureate in chemistry, died on July 26 in Munich.

Born in Solln, near Munich, Fischer served in the German military, going to Poland, France, and Russia during World War II. Taking a brief study leave of absence from the military during the winter of 1942, he began to delve into chemistry at the Technical University of Munich, where his father was a professor of physics.

Later, captured by U.S. soldiers, he was held in a prisoner-of-war camp until repatriation in the fall of 1945. After helping to restore the university from bomb damage, he resumed his studies in 1946 at the Technical University of Munich, earning his doctorate in 1952. In 1955, he took a lecturer position there.

In 1957, Fischer accepted a position as professor at the University of Munich, where he was promoted to senior professor two years later. In 1964, he returned to the Technical University of Munich to serve as chair of its inorganic chemistry department. While there, Fischer shared the 1973 Nobel Prize in Chemistry with Geoffrey Wilkinson of London's Imperial College for their work, performed independently, on the chemistry of organometallic sandwich compounds.

Around this time, Fischer and his team were successfully synthesizing the first carbene and carbyne complexes, heralding a new class of metal complexes and spurring research in the field.

Marcus E. Hobbs, 98, a professor emeritus of chemistry at Duke University who played a bellwether role in the formation of North Carolina's Research Triangle Park, died on Aug., 12, the day after his birthday.

Hobbs earned all of his degrees—an A.B. in 1932, an A.M. in 1934, and a Ph.D. in chemistry in 1936—from Duke. In 1936, he also began a lifelong career in Duke's chemistry department.

He served as chairman of the chemistry department, dean of the Graduate School of Arts & Sciences, dean of the university, vice provost, and provost, as well as authoring or coauthoring more than 50 research papers. He also was a member of the troika created by the board of trustees to manage the university during an interim period before former North Carolina Gov. Terry Sanford was appointed as its president in 1970.

Duke named Hobbs a University Distinguished Service Professor in 1988 and awarded him the University Medal for Distinguished Meritorious Service in 1989.

While serving as dean of the Graduate School of Arts & Sciences, Hobbs was part of a committee that laid the groundwork for Research Triangle Park. He was a charter member of the board of governors of RTI International, a nonprofit organization and the park's first tenant. In 1987, RTI named its 15th building, a $4 million research facility, in Hobbs's honor. In 1999, the board of directors at Research Triangle Foundation presented Hobbs its Archie K. Davis Award in recognition of outstanding service to the research park.

In 1988, Hobbs was the first recipient of the Marcus Hobbs Award of the ACS North Carolina Section, which he chaired in 1946.

He is survived by his daughters, Sara Hobbs Jackson and Joan Hobbs Gray; four grandchildren; and a great-granddaughter.

An emeritus member, he joined ACS in 1937.

Makoto Kumada, 87, a polysilane chemistry pioneer and professor emeritus at Kyoto University, died on June 28 from kidney failure.

Kumada graduated with a doctorate in chemistry from Kyoto University in 1943 and went to work for Toshiba Electric. In 1950, he began his academic career as an assistant professor at newly established Osaka City University. In 1962, he moved to a position as a full professor at Kyoto University, from which he retired in 1983.

In the winter of 1953, when working in his laboratory at Osaka City University, he made a chance discovery that allowed for the production of a polysilane compound in large quantities for the first time, thereby opening doors to organopolysilane chemistry—an area he continued to pursue and develop. Kumada is also credited for helping discover modern transition-metal-catalyzed cross-coupling reactions in the early 1970s.

In 1967, Kumada was awarded the ACS Frederic Stanley Kipping Award in Silicon Chemistry, becoming the first Japanese scientist to win a national award from ACS, which he joined in 1969.

Zbigniew Raciszewski, 85, a Chemical Abstracts Service (CAS) editor, died on July 14 in Granville, Ohio.

Born in Uchanie, Poland, Raciszewski took part in the armed resistance against German occupiers during World War II in his native country. After the war, he studied at Warsaw Agricultural University.

In the early 1950s, he immigrated to Canada and performed research at the University of Saskatchewan, Saskatoon. He then moved to the U.S., earning his Ph.D. in chemistry from the University of Notre Dame.

In his early career, Raciszewski worked in Union Carbide research centers in Parma, Ohio, and South Charleston, W.Va., producing a number of scientific publications. Between 1969 and 1985, he served as a senior editor at CAS in Columbus, Ohio, contributing to the building of its chemical databases. He was a CAS employee for 19 years.

Raciszewski was fluent in five languages and studied the fine arts, especially classical music. He was a member of St. Edward the Confessor Catholic Church in Granville.

In addition to his parents, he was preceded in death by one brother and two sisters. His estate will establish the Zbigniew Raciszewski Fellowship Foundation at the University of Pennsylvania's Wharton School to provide scholarships for students from Poland.


Dmitry M. Rudkevich, 44, an associate professor of chemistry at the University of Texas, Arlington, died from cancer on Aug. 4.

Born in Ukraine, Rudkevich studied chemistry at the Institute of Organic Chemistry within the National Academy of Sciences of Ukraine, the highest state research organization in the country. Before earning his Ph.D. there in 1989, he had served as a member of the Soviet National Guard, responding to the Chernobyl nuclear accident in 1986.

In 1995, Rudkevich went on to complete a second Ph.D. in the laboratory of David N. Reinhoudt at the University of Twente, in the Netherlands. In 1996, he moved to the U.S. to work with Julius Rebek Jr., first at Massachusetts Institute of Technology and later at Scripps Research Institute in La Jolla, Calif. He was also a research assistant professor of the Skaggs Institute for Chemical Biology at Scripps from 1997 to 2001.

He then joined the department of chemistry and biochemistry at the University of Texas, Arlington, as an assistant professor; he was promoted to associate professor in 2004.

Focused on molecular recognition, application of calixarenes, and the supramolecular chemistry of gases, Rudkevich was coauthor of more than 125 scientific papers.

He is survived by his wife of 15 years, Sasha; and two sons, Dmitry Jr. and Eric. He joined ACS in 1996.

Conrad Schuerch, 88, distinguished professor emeritus at the State University of New York College of Environmental Science & Forestry, in Syracuse, died on July 15.
