Some useless but maybe interesting comments:
Michael Faraday discovered that current in one coil would induce current in another coil nearby.
I don"t have the dates exactly, but I think it was around 1830. A few years earlier, another researcher, a Dane named Oersted, accidentally discovered that a current in a wire creates a field around the wire (he noticed that bringing a compass near to the wire caused the needle to move)(Uri Geller tried to show that he could do the same thing using his magical powers; turns out he used tiny magnets). Faraday took up where Oersted had left off. The farad is named for Faraday.
Other useless information: the original condensers were big glass jars (Leyden jars)lined inside and out with foil. Static-electricity generators fed current to each side of the glass. When the current was released, there could be quite a jolt. Seems it was a parlor trick in the late 1700s to shock your guests with current in a Leyden jar.

Other terms named for individuals: Ohm and ampere. Poor Mr. Oersted apparently didn"t get anything named for him.
Some of the writers answering say that the ignition system will work without a condenser.
I have seen engines--way back when--that wouldn"t run when the condenser failed. Has anyone seen an engine run without a condenser?
Perhaps with a very wide gap, to make it hard for the current to jump the gap?

The condenser certainly has the function of keeping the points from burning (because the electrical current "wants" to keep going across the gap and will make a considerable spark without a condenser to absorb the current briefly), but it is also true that if the current continues across the points, there will not be much of a breakdown in the magnetic field across the secondary winding of the coil, hence a very weak or maybe even no spark.
Hope I"m not repeating what others have said.

Today's Featured Article - The Cletrac General GG and the BF Avery A - A Bit of History - by Mike Ballash. This article is a summary of what I have gathered up from various sources on the Gletrac General GG and the B. F. Avery model A tractors. I am quite sure that most of it is accurate. The General GG was made by the Cleveland Tractor Company (Cletrac) of Cleveland, Ohio. Originally the company was called the Cleveland Motor Plow Company which began in 1912, then the Cleveland Tractor Company (1917) and finally Cletrac. ... [Read Article]
