Scott Anguish started developing for the Macintosh in 1984. Upon seeing the NeXT development environment in 1992 he was hooked on the possibilities of a unified imaging model and a pure object-oriented system. In 1994, after several years of NeXT development, he created Stepwise, a portal for information related to NeXT technologies. Today, Stepwise serves as a hub for Apple's Mac OS X technology platform, as well as Cocoa and WebObjects development. Anguish uses Cocoa and WebObjects to build better technology for higher education at the Center for Educational Technology in Middlebury College.
Erik M. Buck is president of EMB & Associates, Inc. He has developed industry-leading applications using the technology that evolved into Cocoa since 1989. He is a frequent contributor to technical mailing lists and has written many articles for the premier Cocoa developer resource on the Internet, www.stepwise.com.
Donald A. Yacktman has been using Cocoa and its predecessor technologies, OpenStep and NextStep, professionally since 1991. He is currently the Vice President of Development at illumineX, an independent software vendor of Cocoa-based Mac OS X software and a WebObjects consulting firm.
