Waldo and Magic, Inc
Waldo:
North Power-Air was in trouble. Their aircraft had begun to crash at an alarming rate, and no one could figure out what was going wrong. Desperate for an answer, they turned to Waldo, the crippled genius who lived in a zero-g home in orbit around Earth. But Waldo had little reason to want to help the rest of humanity -- until he learned that the solution to their problems also held the key to his own...

Magic, Inc.:
Under the guise of an agency for magicians, Magic, Inc. was systematically squeezing out the small independent magicians. Then one businessman stood firm.

Robert A. Heinlein
Robert Anson Heinlein was an American science fiction writer. Often called "the dean of science fiction writers", he was one of the most popular, influential, and controversial authors of the genre. He set a high standard for science and engineering plausibility and helped to raise the genre's standards of literary quality. He was one of the first writers to break into mainstream, general magazines such as The Saturday Evening Post, in the late 1940s, with unvarnished science fiction. He was among the first authors of bestselling, novel-length science fiction in the modern, mass-market era. For many years, Heinlein, Isaac Asimov, and Arthur C. Clarke were known as the "Big Three" of science fiction. ([Source](http://en.wikipedia.org/wiki/Robert_A._Heinlein).)
