D. C. Heath and Company
D.C. Heath and Company was an American publishing company located at 125 Spring Street in Lexington, Massachusetts, specializing in textbooks. History. The company was founded in Boston by Edwin Ginn and Daniel Collamore Heath in 1885. D.C. Heath and Company was owned by Raytheon from 1966 to 1995. When Raytheon exited the textbook market, it sold the company to Houghton Mifflin. D.C. Heath started a small division of software editors to supplement the textbooks in the early 80's. The editors strove to make the software packages independent of the books. There were test banks  that allowed teachers to pick and choose questions for their quizzes and tests. Development was further supported to enable teachers to create their own questions including a formula editor, tagging items by objectives, and including custom graphics in the question as well as in the answer key. This was for the Apple 2 then later Windows and Macintoshes. Many titles were commissioned for the areas of science, math, reading, social studies, and modern languages. These were interactive original programs. D.C. Heath gave this group their own identity, Collamore Educational Publishing. The editors were involved in all facets of the publishing  process including contracts, development, design, publishing, marketing, and sales. Schools were just transitioning from the one computer classroom to the computer lab. In 1988 most of the software was being supported by William K. Bradford Publishing Company composed initially by D. C. Heath / Collamore personnel. Publications-(note: There are far more titles than are listed here)
