Lewis Urry

Died 19 Oct 2004 at age 77 (born 29 Jan 1927).Lewis Frederick Urry was a Canadian-American chemical engineer who invented the ubiquitous alkaline batteries and, later, lithium batteries. After a few years working in Canada for the company that made Eveready batteries, he was transferred in 1955 to its Cleveland, Ohio, laboratory where he began work on a new battery with better life-span than the carbon-zinc type of the time. He succeeded by using manganese dioxide, an alkaline electrolyte and powdered zinc (which he realized had greater surface area than solid zinc). A patent was filed 9 Oct 1957, issued 15 Nov 1960, No. 2,960,558. Production began in 1959. Alkaline batteries are estimated to be 80% of all dry cell batteries now sold in the world. The Smithsonian Institution displays his prototype alkaline battery. Urry held over 50 patents.«

A doctor and a lawyer were attending a cocktail party when the doctor was approached by a man who asked advice on how to handle his ulcer. The doctor mumbled some medical advice, then turned to the lawyer and remarked, 'I never know how to handle the situation when I'm asked for medical advice during a social function. Is it acceptable to send a bill for such advice?'

The lawyer replied that it was certainly acceptable to do so.

The next day, the doctor sent the ulcer-stricken man a bill. The lawyer also sent one to the doctor.
