An American software engineer, highly respected consultant, author, pioneer, and advocate of the practical application of software methods and tools, he worked with John Paul Morrison to refine and promote the concepts of what is now called Flow-based Programming (FBP). He grew up in Missouri, and spent two years in India, where he attended the Woodstock School. In 1967, he earned his M.S. degree in Electrical Engineering from the Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts. He eventually became the chief architect of application development methodology for IBM's consulting group. The annual Stevens Award Lecture on Software Development Methods is named after him. He belonged to the IEEE and the ACM as well as the following honorary societies: Tau Beta Pi, Sigma Xi, and Eta Kappa Nu. He wrote a seminal paper on Structured Design, with Larry Constantine and Glenford Myers in June 1974. IBM Systems Journal 13 (2): 115–139. doi:10.1147/sj.132.0115. This article was the first published on the topic and has been widely reprinted. He was the author of a number of other books and articles on application design methodologies, including: in 1982, “How Data Flow can Improve Application Development Productivity”, IBM System Journal, Vol. 21, No. 2; in 1981, “Using Structured Design: How to make Programs Simple, Changeable, Flexible and Reusable”, John Wiley and Sons; in 1985, “Using Data Flow for Application Development”, Byte; in 1990, “Software Design - Concepts and Methods”, Practical Software Engineering Series, Ed. Allen Macro, Prentice Hall; "Integrating Applications with SAA (Systems Application Architecture)", with L.A. Buchwald & R. W. Davison. In: IBM Systems Journal, Vol 27 No 3, pp 315–324, 1988; "Structured Design, Structured Analysis, and Structured Programming", In: American Programmer, Nov. 1991; and "Data Flow Analysis and Design", In: Encyclopedia of Software Engineering. John J. Marciniak, Editor-in-Chief, Volume 1, pp 242 – 247, John Wiley & Sons, Inc, 1994. He died in Fairfield, CT in 1993.
