All I can dig up is that it was patented by Frederick W. Schwinn, patented June 5, 1945
It is said that tandem bikes were invented by Mikael Pederson in the 19th century who patented his tandem version of his Pederson bicycle around 1898.
In a tandem, two or more riders sit behind each other. In 1898, in England, Danish inventor Mikael Pedersen developed a two-rider tandem version of his Pedersen bicycle. This was the first tandem.
Normally, two. There are usually only two seats on a tandem bike.

Bike rider, randonneur.
You're probably thinking of a tandem
Don't think there's ever been a serially produced bike with 12 pedals. Somewhere, on some occasion, someone has probably put together a 6-seater bike in the in-line, tandem configuration, which would have 12 pedals.
The one who works the hardest.
Usually, yes. But a true tandem will have two sets of pedals as well. There are a few bikes that can have two seats w/o having two pedals, these are usually considered cargo bikes instead.
A tandem bike has two seats, and two handle bars. The seats are NOT side by side, and the only the front steering wheel can turn. They make tandem bicycles for adults, but there are a lot of tandem bikes that are designed for an adult in front and a child in the back.

A tandem bicycle is a bike for two riders, one after the other, with a set of pedals for each. A 10-speed bike can be two different things. Either a bike with two chainrings by the pedals and five sprockets at the rear wheel, or if it's a newer bike, 10 sprockets at the rear.
