About the author

Edward S. Popko is a graduate of the University of Detroit’s School of Architecture and has both Masters and PhD degrees from Massachusetts Institute of Technology. He is a registered architect and former Fulbright Scholar. In the 1960s, he was an apprentice in Buckminster Fuller’s affiliate office, Geometrics, Inc., in Cambridge, Massachusetts, and later authored Geodesics, a primer on geodesic domes, and Transitions, a documentary of urban settlements in developing countries.
For the past 25 years, he has held research, product development, and marketing positions for Computer Aided Design and Geographic Information Systems technology within IBM. He has managed software development teams in computer mapping and CAD solutions for architects, industrial buildings, high‐tech plants, and shipbuilding.
He is retired from IBM and lives with his wife, Geraldine, in Woodstock, New York. They have a daughter Ellen and a son Gerald.
Christopher J. Kitrick is a graduate of the University of Cincinnati with a bachelor's in Architecture and a masters in Structural Engineering. In the late 1970s he interned for 3 years at Buckminster Fuller's professor emeritus office on the campus of the University of Philadelphia. During that tenure he was involved in Fuller's Synergetics II book, multiple dome developments, tensegrity research, and the first computerized version edition of the Dymaxion Air‐Ocean map.
For the past 36 years he has been involved with graphics software and hardware development from mainframe to mobile devices enabling the rapid advancement of visual technology. Independently he has authored and presented numerous technical papers on spherical geometry at international conferences on space structures.
He is still working and resides in La Jolla, California, with his wife Tomoko. They have two sons Francis and Ian, and one daughter, Eileen.
