Carl Gassner

Born 17 Nov 1855; died 31 Jan 1942 at age 86.German physician and inventor who was an eyes and ears specialist, but is best known for inventing the first dry cell battery (1886). It used the same principle as the Leclanché cell. A carbon manganese rod was the anode. Instead of a liquid electrolyte, he devised a porous paste form with sal ammoniac, plaster, zinc chloride and water. All were sealed in a a zinc can that also was the cathode. Lechanché cells had been used for electric door bells, but those were vulnerable to breakage and spillage, as well as needing fresh water added periodically. To help a store-keeper, Gessner devised his dry cell as an better alternative.He obtained a German patent (8 Apr 1886), a British provisional patent (No. 18,754 on 22 Dec 1888), and a U.S. patent (No. 373,064 on 15 Nov 1887) as well as patents in Austria-Hungary, Belgium and France.«

A father put his three year ol...

A father put his three year old daughter to bed, told her a story and listened to her prayers which she ended by saying, "God bless Mommy, God bless daddy, God bless grandma and good-bye grandpa."
The father asked, "Why did you say good-bye grandpa?"
The little girl said, "I don't know daddy, it just seemed like the thing to do."
The next day grandpa died.
The father thought it was a strange coincidence.
A few months later the father put the girl to bed and listened to her prayers, which went like this: "God bless Mommy, God Bless daddy, and good-bye grandma."
The next day the grandmother died.
"Oh, my gosh", thought the father, "this kid is in contact with the other side."
Several weeks later when the girl was going to bed the dad heard her say: "God bless Mommy and good-bye daddy."
He practically went into shock. He couldn't sleep all night and got up at the crack of dawn to go to his office. He was nervous as a cat all day, had lunch sent in and watched the clock.
He figured if he could get by until midnight he would be okay. He felt safe in the office, so instead of going home at the end of the day he stayed there, drinking coffee, looking at his watch and jumping at every sound. Finally midnight arrived, he breathed a sigh of relief and went home.
When he got home his wife said "I've never seen you work so late, what's the matter?"
He said, "I don't want to talk about it, I've just spent the worst day of my life."
She said, "You think you had a bad day, you'll never believe what happened to me. This morning the milkman dropped dead on our porch."
