William C. KellyBorn 21 Aug 1811; died 11 Feb 1888 at age 76.American ironmaster who invented the pneumatic process of making steel. While a Kentucky manufacturer of iron kettles, he discovered that cold air blown on red-hot iron caused the metal to become white-hot by igniting the carbon and thus eliminating impurities. He applied his “air boiling”technique to his own product, but his customers decried “Kelly's fool steel,”and his business declined. In a legal fight, by asserting his practical efforts investigating the process had been carried out earlier in time, his belated patent of 23 Jun 1857 won priority over the U.S. patent of Sir Henry Bessemer of Great Britain. However, Kelly's invention was only a first step. They jointly licenced their patents. Bessemer's further developments were more successful. The Bessemer-Kelly process won acceptance, produced the first inexpensive steel, and furthered the industrial age.«
Baseball In Heaven
Abe turns to Sol and says, "Do you think there's baseball in heaven?"
Sol thinks about it for a minute and replies, "I dunno. But let's make a deal: if I die first, I'll come back and tell you if there's baseball in heaven, and if you die first, you do the same."
They shake on it and sadly, a few months later, poor Abe passes on.
One day soon afterward, Sol is sitting there feeding the pigeons by himself when he hears a voice whisper, "Sol... Sol..."
Sol responds, "Abe! Is that you?"
"Yes it is, Sol," whispers Abe's ghost.
Sol, still amazed, asks, "So, is there baseball in heaven?"
"Well," says Abe, "I've got good news and bad news."
"Gimme the good news first," says Sol.
Abe says, "Well... there is baseball in heaven."
Sol says, "That's great! What news could be bad enough to ruin that!?"
Abe sighs and whispers, "You're pitching on Friday."
