Cecil H. Jensen authored or coauthored many successful technical books, including Engineering Drawing and Design, Fundamentals of Engineering Drawing, Fundamentals of Engineering Graphics (formerly called Drafting Fundamentals), Interpreting Engineering Drawings, Geometric Dimensioning and Tolerancing for Engineering and Manufacturing Technology, Architectural Drawing and Design for Residential Construction, Home Planning and Design, and Interior Design. Some of these books were printed in three languages and are popular in many countries.
Mr. Jensen was a member of the Canadian Standards Committee (CSA) on Technical Drawings (which includes both mechanical and architectural drawing) and headed the Committee on Dimensioning and Tolerancing. He was Canada’s ANSI representative. He represented Canada at two world ISO conferences in Oslo and Paris on the standardization of technical drawings. Cecil Jensen passed away in April, 2005.
Jay D. Helsel
Jay D. Helsel is professor emeritus of applied engineering and technology at California University of Pennsylvania.

He coauthored Engineering Drawing and Design, Fundamentals of Engineering Drawing, Programmed Blueprint Reading, the popular high school drafting textbook Mechanical Drawing: Board and CAD Techniques, now in its thirteenth edition, and Interpreting Engineering Drawings.Dennis R. Short
Dennis R. Short is professor of computer graphics technology at the School of Technology, Purdue University. He completed his undergraduate and graduate work at Purdue University and also studied at the University of Maryland, College Park. He enjoys teaching traditional engineering design and drafting, computer-aided drafting and design, computer-integrated manufacturing (CIM), and advanced modeling and animation. While at Purdue, he implemented the first instructional CAD system for the School of Technology, as well as the first networked PC-based CAD laboratory. In addition to teaching undergraduates, he is on the graduate faculty. He codirects the Purdue International Center for Entertainment Technology (PICET), a university-level interdisciplinary research and development center. Dr. Short prepared the Instructor Wraparound Edition for Engineering Drawing and Design, Fifth and Sixth Editions.
