Len Bass

Leonard Joel (Len) Bass (born c.1943) is an American software engineer, Emeritus professor and former researcher at the Software Engineering Institute (SEI), particularly known for his contributions on software architecture in practice.

Biography
Bass received his Ph.D. degree in Computer Science from Purdue University in 1970 under the supervision of Paul Ruel Young with the thesis, entitled "Hierarchies based on computational complexity and irregularities of class determining measured sets."

Bass was appointed Professor of Computer Science at the University of Rhode Island in 1970. In 1986, he moved to the Software Engineering Institute at Carnegie Mellon University, where he started as head of the user-interface software group, and later focused on the analysis of software architectures. Since 2011, he has been Senior Principal Researcher at NICTA (National ICT Australia).

Len Bass was awarded the Software Development Magazine's Jolt Productivity Award twice in 1999 and 2003.
