Tom founded ProductivityProductsInternational, later to become StepStone, where he and BradCox developed and took ObjectiveCee to market.
Tom is a long time admirer of the Macintosh. (He designed parts of his Connecticut home on one.) Tom must have been proud to see SteveJobs adopt Objective-C, though it doesn't seem to have made him rich.
Tom is presently (May 2003) a principal of Shoulders Corporation (http://www.shoulderscorp.com), a software services firm in Connecticut.
