Have just come across this wonderful story, which I'm sure some of you will enjoy. Whilst researching the best way to pollinate indoor tomatoes (with an electric toothbrush - without the bristly bit, apparently it imitates the frequency of the bumblebees wing-flap) I came upon the story behind the name of a particular tomato. All thanks to wikipedia;
Mortgage lifter is the name given to a cultivar of tomato developed by M.C. Byles, also known as "Radiator Charlie", because he used it to save his house, selling it for a dollar per plant (back in the 1940s, when "a dollar meant something") in order to pay off his mortgage. When his radiator repair business slumped during the Great Depression, he started cross-breeding his four best tomato plants, until he came up with a stable derivation which he felt tasted better and had larger fruit. He promoted it as being able to feed a family of six, therefore getting the sky-high price of one dollar per plant, and paying off his house in just four years.
