Mitsuru Hanada

Sumo Wrestler

Mitsuru Hanada, 55, the Prince of Sumo who hailed from one of the sport's most powerful dynasties and rose to the second-highest rank of ozeki, died May 30 at a hospital in Tokyo. He had mouth cancer.

Mr. Hanada, more commonly known by his title as stablemaster Futagoyama, spent a 16-year career in the ring. He was the father of the immensely popular brothers Takanohana and Wakanohana, former yokozunas who dominated the sport in the 1990s.

Mr. Hanada also fought under the ring name of Takanohana. He rose to sumo's top makuuchi division at the record early age of 18 under the training of his elder brother, Katsuji, the first Wakanohana and also a grand champion.

He never reached sumo's top rank of yokozuna despite winning two Emperor's Cups. He retired in 1981 and became director of the Japan Sumo Association.

Martin J. Durkan Sr.

Washington State Lawmaker

Martin J. Durkan Sr., 81, a Democratic powerhouse and patriarch of a leading family in Washington state law and politics, died May 29 at Maui Memorial Medical Center in Hawaii, where he and his wife had a vacation home. No cause of death was reported.

Mr. Durkan, a Democrat, was conservative on social issues but liberal on environmental and economic matters. After a two-year term in the state House, he spent 18 years in the state Senate starting in 1958 and gained power as chairman of the budget-writing Senate Ways and Means Committee in the late 1960s. He helped to write some of the early state legislation on oil spills and sponsored the bill that established the state Ecology Department.

Mr. Durkan voted against the Equal Rights Amendment, but on labor and economic issues was known for caring about the disadvantaged and forgotten. He pushed farm worker housing although his urban Seattle district was far from agricultural areas and the effort brought him no votes.

Mr. Durkan ran for governor in 1968 and 1972 but lost both times in the Democratic primary and met the same fate when he ran for Congress in 1977. In the succeeding years, he became one of the best-paid and most effective lobbyists in Olympia, Wash. His clients included the state's horse racing industry.

Physics Professor

David Powley DeWitt, 71, a retired Purdue University physics professor and an expert on heat transfer at the National Institute of Standards and Technology, died May 17 of complications from primary amyloidosis at his home in Edgewater.

Dr. DeWitt was born in Bethlehem, Pa., and graduated from Duke University in 1955 with a degree in mechanical engineering. He received his master's degree in heat and mass transfer/thermodynamics from the Massachusetts Institute of Technology in 1957 and his doctorate in thermophysics from Purdue University in 1963.

As a physicist at the National Bureau of Standards and as a physics professor at Purdue for many years, he worked on measurement methods in support of thermal control space applications.

At the National Institute of Standards and Technology in Gaithersburg from 1997 to 2004, he was a physical scientist in the Optical Technology Division of the Physics Laboratory. He led an effort to provide standards for the measurement of heat flux to help improve the safely and performance of aerospace vehicles.
