Illustrate about the three authors of IGES

In 1977, the three authors of The Initial Graphics Exchange Specification were recognized collectively for their contributions to the development of IGES Version 1.0 by receiving the AIMTECH Joseph Marie Jacquard Memorial Award. The first author, Roger Nagel, was a NBS staff member at the time and is now the Harvey Wagner Professor of Manufacturing Systems Engineering in the Electrical Engineering and Computer Science Department at Lehigh University. He created Lehigh's Robotics Research Institute, established and directed the Manufacturing Systems Engineering Program, and served as Executive Director of Lehigh's Iacocca Institute for Competitiveness Research. While an employee of NIST, Nagel was a key member of the scientific team developing the Factory Hierarchical Control System in the Robotics Group. This work on hierarchical control systems, performed with James Albus, Tony Barbera, and Gordon Vanderbrug, has been the basis of hundreds of computer-based control systems for automation over the last 20 years. Nagel continues to serve as a technical advisor and consultant to NIST's Manufacturing Engineering Laboratory.

The other two authors were from industry. Walt Braithwaite is currently Corporate Vice President for Company Offices Administration at the Boeing Company. He has held numerous positions within Boeing, including Director of Program Management for the 737 and 757 airplane programsand Chief of Engineering Operations for the 747 and 767 programs. As the lead engineer responsible for technical direction in developing an information network to integrate computer-aided design and computer-aided manufacturing, he led development of Boeing's common data format andtranslators, which were used as a basis for developing the IGES protocol. Philip Kennicott joined the General Electric Research Laboratory in 1961 where he made contributions in the fields of x-ray crystallography and spark-source mass spectrography. As a consultant to General Electric's Computer Aided Design Center, he was instrumental in making General Electric the largest user of CAD/CAM equipment in the world in the 1970s. This work led to the concept of a neutral database, the basis for the General Electric contribution to IGES. Within the IGES community, Kennicott served as a leader of many technical activities, including Editor of the continually evolving IGES standard. He also led a technical team to develop the Department of Energy Data Exchange Format, the first IGES application protocol. He continued this work at Sandia National Laboratories in 1989 and retired from Sandia in 1997.
