Morris walks out into the street and manages to get a taxi just going by. He gets into the taxi, and the cab driver says, "Perfect timing. You're just like Dave."
"Who?"
"Dave Aronson. There's a guy who did everything right. Like my coming along when you needed a cab. It would have happened like that to Dave."
"There are always a few clouds over everybody," says Morris.
"Not Dave. He was a terrific athlete. He could have gone on the pro tour in tennis. He could golf with the pros. He sang like an opera baritone and danced like a Broadway star."
"He was something, huh?"
"He had a memory like a trap. Could remember everybody's birthday. He knew all about wine, which fork to eat with. He could fix anything. Not like me. I change a fuse, and I black out the whole neighborhood."
"No wonder you remember him."
"Well, I never actually met Dave."
"Then how do you know so much about him?" asks Morris.
"Because I married his widow."

Dry-cell patent

In 1887, German scientist, Dr. Carl Gassner, was issued a U.S. patent (No. 373,064), the first in the U.S. for a “dry” cell. Gassner had already patented his invention in Germany (No. 37,758) on 8 Apr 1886, and also in Austria, Belgium, England, France and Hungary in the same year. The sealed zinc shell which contained all the chemicals was also the negative electrode. Later, he improved the shelf life of the battery by adding zinc chloride to the electrolyte to reduce corrosion of the zinc shell. Gassner's battery was much like the carbon-zinc, general-purpose batteries sold today. By 1896, the National Carbide Company (later Union Carbide and Eveready) produced the first consumer dry cell battery. Two years later, the company made the first D cell.«[Image: The six-inch, 1.5 volt Columbia Dry Cell marketed by NCC in 1896.]
