As a young entrepreneur he graduated from the venerable Borphee Business School and at age 22, he founded Flathead Industries with a purpose to invent other companies, which it would then sell to FrobozzCo International. Within three years, FI had an annual income of 80,000,000 zorkmids.
Eventually, the conglomerate decided to buy FI, renaming it the Frobozz Magic Company Company. John D. became one of FrobozzCo's 39,000 vice-presidents. It didn't take John D. long to parlay his business acumen and royal connections into the chairmanship of FrobozzCo. Years heady growth followed.
When John D.'s older brother Dimwit became king, FrobozzCo received every contract for Dimwit's incredible projects. Hundreds of new subsidiaries were formed daily; in 781 GUE a huge 400-story headquarters opened in Flatheadia. John D.'s long time goal was for FrobozzCo to control every single zorkmid of commerce in the Great Underground Empire.
When that happened, John D. was touring the factories of the Frobozz Magic Snowmaking Equipment Company in the Gray Mountains with a huge entourage, when they disappeared. He never learned that the lone holdout, a small rutabaga farm in Mithicus, finally sold out to FrobozzCo in 789 GUE, fulfilling his goal.
- John D. is named after American entrepreneur John D. Rockefeller.
