He invented the high resistance filament allowing bulbs to be used in parallel rather than in series. The vacuum technique was invented 20 years before he began working on incandescent lights. He greatly improved the quality of the vacuum, but I recall that was mainly by using vacuum pumps invented by other people. He got one of the best pumps in the world on loan from U. Connecticut and apparently never returned it. He invented a whole slew of other things relating to bulbs, such as the method of screwing them in, fabrication techniques, improved generators, and power metering. - Jed
