Paul W. Abrahams, Sc.D., CCP, is the author of TeX for the Impatient, a book whose success inspiredUNIX for the Impatient. A consulting computer scientist and past president of the Association for Computing Machinery, he specializes in programming languages, design and implementation of software systems, and technical writing. He received his bachelor's degree in mathematics from the Massachusetts Institute of Technology in 1956 and his doctorate in mathematics there in 1963, studying artificial intelligence under Marvin Minsky and John McCarthy and writing his dissertation on "Machine Verification of Mathematical Proof". He is one of the designers of the first LISP system and also the designer of the CIMS PL/I system, which he developed while a professor at New York University. He also participated in the design of the Software Engineering Design Language (SEDL), developed at the IBM T.J. Watson Laboratories. Currently he is working on the design of SPLASH, a Systems Programming LAnguage for Software Hackers and on a new book, OS/2 for the Impatient. In 1995 he was honored as a Fellow of the ACM. Paul resides in Deerfield, Massachusetts, where he writes, hacks, hikes, hunts wild mushrooms, and listens to classical music. His Internet address is email@example.com.
Bruce R. Larson is the founder of Integral Resources, a systems integration and UNIX consulting firm, a co-founder of BRInet (1995), which provides Internet connection and consulting services, and a partner in Internet Exchange Limited (1994), which provides dialup and ISDN connectivity in the Boston area. His specialties are shell tools, systems programming, IP and X.25 networks, performance monitoring, software integration, mail systems, and security. He has worked with Solaris, AIX, HPUX, IRIX, SCO UNIX, and other Intel-based UNIX systems. His experience includes configuring and administering Internet domains and connecting UNIX systems to X.25 networks, as well as designing and implementing custom installation scripts, kernel-level data extraction tools, shell tools, a software message switch, and IP-based utilities. From 1979 to 1981, he did software modeling for the Federal Aviation Authority under a grant from the U.S. Department of Transportation; in 1988 he received his bachelor's degree in pure mathematics from the University of Massachusetts at Boston. A member of UniForum, the IEEE Computer Society, and the American Mathematical Society, Bruce resides in Milton, Massachusetts. His Internet address is firstname.lastname@example.org
