Ralph Tekel, 94, of Center City, a retired La Salle University chemistry professor who as a graduate student contributed to the Manhattan Project - albeit without his knowledge - died Wednesday, Oct. 8, of pneumonia at Thomas Jefferson University Hospital. According to his daughter Billie Elias, in 1944 Dr. Tekel was part of a research team led by Dr. Henry Hass at Purdue University called Project 220. The team was asked to prepare Freon-like materials called fluorocarbons, Elias said.

Robert R. Jones Sr., 93, formerly of Warminster, a statistician who worked on the Manhattan Project during World War II, died of Alzheimer's disease Saturday, Nov. 16, at Southampton Estates. Mr. Jones was among the specialists and scientists who worked in secret to build the atomic bomb during World War II, he told the Hatboro Public Spirit in a 2004 interview. Equipped with a bachelor's degree from Columbia University in statistics but unfit for military service due to a punctured eardrum, he initially went to work for the DuPont Co. in Connecticut.

Robert F. Christy, 96, a former California Institute of Technology professor who helped design the trigger mechanism for the atomic bombs used in World War II, died of natural causes Wednesday at his home in Pasadena, Calif., according to Caltech spokeswoman Deborah Williams-Hedges. Mr. Christy was one of the early recruits to the Manhattan Project at Los Alamos Laboratory, a U.S. government research project to develop atomic weapons during the war. He was handpicked to join by his University of California, Berkeley, professor J. Robert Oppenheimer, with whom Mr. Christy studied quantum mechanics.

As with many husbands on Thanksgiving, Daniel D. Friel Sr. was asked by his wife to carve the big turkey. But when the soon-to-retire DuPont Co. executive tried to find a knife with a decent edge, he came up empty. "He attempted to sharpen them with what tools he had, and he found they didn't work. He basically made a mess of the turkey," Mr. Friel's son, Daniel Jr., said. That experience led Mr. Friel Sr. to his life's Act II: founding EdgeCraft Corporation in Avondale, Pa., and developing the popular Chef'sChoice® line of culinary tools, including knife sharpeners, food slicers, and waffle makers.

Few major modern operas enter the world with so little critical consensus as Doctor Atomic. Embraced and dismissed but not for consistent reasons, John Adams' opera about the invention of the atomic bomb made the rounds in San Francisco, Chicago, Amsterdam, but arrived at the Metropolitan Opera on Monday with a twist. Instead of the original Peter Sellars production, British filmmaker Penny Woolcock (whose movie version of Adams' The Death of Klinghoffer is maybe the best-ever opera film)

William J. Prichard, 90, of West Brandywine and Havertown, a research chemist who worked on the Manhattan Project during World War II and an avid photographer, died Feb. 21 at Brandywine Hospital of heart arrhythmia. A resident of Freedom Village retirement community in West Brandywine, Mr. Prichard lived in Havertown for most of his life and spent his happiest hours sailing on the Chesapeake Bay or using his chemical knowledge in the darkroom, experimenting with unusual techniques in printing black-and white photographs.

Hermann Lisco, a gifted scientist and legendary teacher, died last week. He was a quiet man from an unquiet place. German-born, he received his medical degree from the University of Berlin in 1936, came to the United States to teach pathology at Johns Hopkins University, and was recruited to the Manhattan Project. In secret, he worked with a team of scientists at the University of Chicago studying the biological effects of a strange new human creation: plutonium. Later, he was flown to Los Alamos to study the first person ever to be killed by acute radiation poisoning.

Two things came together in the last few days to make me think that the world is less predictable - and less threatening - than it might seem. I've been teaching part of a course called the Drexel Symposium in which we look at a single subject from a variety of perspectives. Our topic this term was the atomic bomb. We've been bringing in guest lecturers to talk about nuclear weapons from their particular vantage points - physics, engineering, history, even myth and legend.

In the early 1940s, the company Harold Pugh worked for became involved in a top-secret project involving a large power plant in Washington state. Pugh didn't know exactly what the project was, only that it had the highest security classification. As it turned out, his employer - the Darby-based Roberts Filter Group - had contracted to supply all the water-filtration systems for the Manhattan Project, which had facilities around the country. Only after the United States dropped the world's first atomic bomb on Japan in 1945 did Pugh find out what was going on. "You ought to see the letters we got," Pugh, 85, said last week as he made a leisurely recovery from a party the day before.

George J. Nessle, 74, formerly of Montgomery County, a retired chemist who worked on the World War II Manhattan Project to develop the atomic bomb, died Feb. 16 at his home in St. Petersburg Beach, Fla. Mr. Nessle was born in Corning, N.Y., and graduated from Corning Free Academy High School in 1939. He earned a degree in chemistry from the University of Michigan in 1943. From May 1943 to June 1944, he worked for Corning Glass Works in development and manufacture of the Norden Bomb Sight, a device that greatly increased the accuracy of Allied bombing of Germany.
