Grady Booch (unknown - .)
Booch gained his bachelor of science from the United States Air Force Academy in 1977 and his master of science in electrical engineering from the University of California at Santa Barbara in 1979. He has been chief scientist at (IBM) Rational since its foundation in 1981. Booch contributed significantly to the development of object-oriented thinking and created the booch method and a number of software products including one of the first OO modeling tools - 'Rational Rose'. He is renowned as one of the original developers of the UML along with Ivar Jacobson and James Rumbaugh. Booch has published widely but his two most significant works are 'The Unified Modeling User Guide' and Object-Oriented Analysis and Design with Applications. He has contributed significantly to the application of architecture to complex analysis and design problems.
