Arthur Jeffrey Dempster

Born 14 Aug 1886; died 11 Mar 1950 at age 63.Canadian-American physicist who in 1918 built the first mass spectrometer (based on the invention of Francis W. Aston) and discovered isotope uranium-235 (1935). The mass spectrometer is an instrument that uses electric and magnetic fields to separate and measure a sample's atoms according to their mass and relative quantity. In 1935, he discovered that naturally occurring uranium, though mostly uranium-238, contained 0.7% U-235 (later used as the primary fuel in atomic bombs and reactors after Niels Bohr predicted it could be used to produce a chain reaction releasing huge amounts of nuclear fission energy). During WW II, Dempster worked with the secret Manhattan Project that developed the world's first nuclear weapons.«

Potty Trained

While carpenters were working outside the old house I had just bought, I busied myself with indoor cleaning. I had just finished washing the floor when one of the workmen asked to use the bathroom.

With dismay I looked from his muddy boots to my newly scrubbed floors. “Just a minute,” I said, thinking of a quick solution. “I’ll put down newspapers.”

“That’s all right, lady,” he responded. “I’m already trained.”
