LEXINGTON, Mass. (AP) _ Kenneth Tompkins Bainbridge, a scientist who accurately measured atomic weights and director of the first atomic bomb test at Alamagordo, N.M., died Sunday. He was 91.

While a postgraduate fellow at Bartol Laboratory in Swarthmore, Pa., Bainbridge built a mass spectrometer to search for the then-undiscovered Element 87, called eka-cesium.

The instrument was so accurate it could measure the weights of atoms and their nuclei, as well as distinguish the weight difference of various isotopes of an element.

Bainbridge and another scientist stumbled on classified work when they devised a pump to separate the fissionable Uranium 235 from its stable isotope, Uranium 238.

In the summer of 1943, Bainbridge was a group leader for the Manhattan Project at Los Almos, N.M. The next year, he was named director of the Trinity project, which exploded the first atomic bomb _ a plutonium bomb _ on July 16, 1945.

Chas Chandler

NEWCASTLE-UPON-TYNE, England (AP) _ Chas Chandler, producer of Jimi Hendrix's first two albums and bass player on the 1960s hit ``The House of The Rising Sun,'' died Wednesday after undergoing tests for an aortic aneurysm. He was 57.

Chandler was playing in the Alan Price Trio in 1962 when vocalist Eric Burdon joined the band. They renamed the group The Animals.

Their first hit song was ``Rising Sun'' in 1964, followed by others including ``Don't Let Me Be Misunderstood,'' ``Bring It On Home to Me'' and ``We've Gotta Get out of this Place.''

Chandler turned to managing other rock stars and produced the first two Hendrix albums, ``Are You Experienced?'' and ``Axis: Bold as Love,'' but quit halfway through ``Electric Ladyland,'' frustrated with the hangers-on and endless re-recording of tracks.

Chandler went on to manage other groups. Recently, he and his business partner Nigel Stanger, a one-time Animals saxophonist, developed Newcastle Arena, a 10,500-seat sports and entertainment venue that opened last year.

Bud Foster

MADISON, Wis. (AP) _ Bud Foster, who coached Wisconsin to its only NCAA basketball championship, died Tuesday at 90.

Foster, who coached Wisconsin teams from 1934 to 1959, also played basketball for the Badgers from 1928 to 1930.

He compiled a 265-267 record in his 25 years as basketball coach, three Big Ten championships, two trips to the NCAA tournament and the 1941 NCAA title.

Ferd Hernandez

OMAHA, Neb. (AP) _ Ferd Hernandez, once the second-ranked middleweight boxer in the world, died Wednesday of liver disease. He was 57.

Hernandez, ranked behind only Nino Benvenuti of Rome in the late 1960s by the World Boxing Association, compiled a 65-12 professional record before an eye injury forced his retirement. He later refereed bouts and worked as a bartender in Las Vegas.

Paul Touvier

PARIS (AP) _ Paul Touvier, the only Frenchman convicted of World War II crimes against humanity, died Wednesday after serving two years in prison for the reprisal executions of seven Jews. He was 81 and had prostate cancer.

Touvier, who ordered the 1944 executions to avenge the assassination of the Vichy propaganda chief, spent much of his life on the run, living off handouts until he was arrested in 1989.

Touvier was head of the Lyon-area militia for the Vichy regime, which collaborated with the Nazi occupation of France. He claimed that he was acting under German orders and that he actually saved 93 Jews by sacrificing seven, but that was never proven.

Touvier was a key aide to Gestapo chief Klaus Barbie, who was the only other man to stand trial in France for crimes against humanity committed during World War II.

Though Touvier's conviction in 1987 satisfied many Jewish groups, he is widely regarded by historians as having played a secondary role in the arrest and deportation of Jews during World War II.
