The IBM Selectric was introduced in 1961 (just like me!), and was revolutionary, in that the platen does not move, but instead the type element moves. The single type element (ball) has 88 characters on it, in 4 rows. This typewriter is a model 72, with a cloth ribbon in a plastic cartridge. It is a narrow platen model, they were available in 3 widths that I know of.
The first keyboard to have a Shift key was introduced on the Remington No. 2 typewriter introduced in 1878 that had one Shift key on the left side of the keyboard.

The first Underwood typewriter was invented by Franz Xaver Wagner who patented the typewriter April 27, 1893, U.S. patent 523,698.
