Non-profit organizations are not in business to make a profit. This simple but significant issue points to the absence of profits or losses in the non-profit world--a major difference as compared with the for-profit firms.
Dr. Seuss had no children and, despite authoring children's books, he was neither fond of nor comfortable around those of others. He would brag about a daughter, Chrysanthemum-Pearl, but she was a work of fiction.
Seuss was Theodor Geisel's middle name, and also his mother's maiden name (Henrietta Seuss Geisel). Geisel drew cartoons for the newspaper while attending Dartmouth College, and always signed them Seuss. Some of his other pseudonyms were Theo LeSieg, Rosetta Stone and Theophrastus Seuss.
