### An engineer was crossing a roa...

An engineer was crossing a road one day when a frog called out to him and said, "If you kiss me, I'll turn into a beautiful princess."He bent over, picked up the frog and put it in his pocket.
The frog spoke up again and said, "If you kiss me and turn me back into a beautiful princess, I will stay with you for one week."
The engineer took the frog out of his pocket, smiled at it and returned it to the pocket.
The frog then cried out, "If you kiss me and turn me back into a princess, I'll stay with you and do ANYTHING you want."
Again the engineer took the frog out, smiled at it and put it back into his pocket.
Finally, the frog asked, "What is the matter? I've told you I'm a beautiful princess, that I'll stay with you for a week and do anything you want. Why won't you kiss me?"
The engineer said, "Look I'm an engineer.
I don't have time for a girlfriend, but a talking frog, now that's cool."

### Robert E. Gottschalk

Died 3 Jun 1982 at age 64 (born 12 Mar 1918).American inventor and business executive who was president of Panavision Inc., a company he helped found in 1953, to create a wide-screen film movie process. It manufactured and leased equipment. Panavision is an anamorphic system, using a 65mm negative and a 70mm print, projected in a letterbox shape with a 2.66 to 1 ratio. Gottschalk developed specially designed lenses used during capture and projection that worked with an image recorded on the film that is compressed horizontally. An unmodified widescreen image would occupy only half the area of a standard 1.33 to 1 film frame, wasting space above and below. Lateral compression fills the frame using an image with modified aspect ratio on the film, that retains more detail in the vertical resolution, and reduces the appearance of grain when projected. He died by murder at his home.«
