How did a couple of auto mechanics from East Cambridge, Mass. Become national radio stars...on NPR yet?

Well, for as long as they can remember. The Brothers Magliozzi loved to take things apart to see how they work and then put them back together again over and over.

Both graduated from the prestigious MIT; following which Ray began teaching and Tom decided to hang out in the corporate world for a short time. Eventually, they got together in a venture they call "Hacker's Heaven", a garage where people could do their own car work and the Magliozzi's would rent space and tools to them. But they ended up fixing most of the cars themselves anyway.

Since their business was new and different, people knew about the brothers and they were asked to appear on a panel of automotive experts at WBUR, the Boston NPR affiliate...and pretty soon the show was theirs. Ten years later it was launched as a full national network program.

Today, Tom writes and hosts "Car Talk" while brother Ray runs the garage and hosts "Car Talk", obviously to the delight of millions of people in the world.
