Frederick P. Brooks Jr. (1931-2022) was a computer architect, software engineer, and academic whose work shaped the field of project management—most especially software management—through the later 20th century and into the 21st century. Most widely known for his role as project manager for IBM’s System/360 hardware and, later, the OS/360 software project, Brooks gained firsthand experience with the immense challenges of large-scale development. This experience forms the foundation of The Mythical Man-Month, a collection of essays that analyzes why software projects are uniquely difficult to manage. 

Brooks was born in Durham, North Carolina, in 1931. His university education took him into the newly emerging field of computer science in the 1950s. He graduated in physics from Duke University in 1953, going on to study for a PhD in applied mathematics (computer science) at Harvard University in 1956. As a postgraduate student, Brooks was a teaching assistant in Harvard's "automatic data processing" graduate program, the first of its type in the world. 

Brooks started working for IBM in 1956, based in New York. He worked on developing the IBM 7030 Stretch, a $10 million scientific supercomputer sold onto the market, and the IBM 7950 Harvest, a computer for the National Security Agency. Following this, he became manager for developing the IBM System/360 family of computers and the OS/360 software package. The IBM System/360 was launched in 1964 as a revolutionary system which offered a unified architecture across different models for business and science, The [project faced significant delays, especially in relation to OS/360 operating system, The purpose of The Mythical Man-Month is to distill the hard-won lessons from the OS/360 project into principles for a this new discipline that Brooks called “software engineering.” The term “computer architecture” is also attributed to Brooks, meaning the design structure of a computer, dictating how the software and hardware interact. 

Following his work at IBM, Brooks was invited to establish a new computer science department at The University of North Carolina (UNC) at Chapel Hill, in 1964. He was the founding Kenan Professor of Computer Science at UNC until his retirement in 2015 and acted as faculty chair until 1984. It was while teaching and researching at UNC that Brooks wrote and published The Mythical Man-Month, combining his professional project experience at IBM with his subsequent research and academic methodologies. Brooks authored and co-authored many other works during this time, most notably Automatic Data Processing (1969), “No Silver Bullet” (1987, reprinted in the 1995 edition of The Mythical Man-Month), Computer Architecture (1997), and The Design of Design (2010). Brooks was given numerous awards and honorary positions for his contribution to the fields of computer science and project management, including the National Medal of Technology and Innovation (1985) and the Turing Award from the Association for Computing Machinery (1999).

Brooks died at Chapel Hill in 2022, aged 91. In its obituary of Brooks, the New York Times called The Mythical Man-Month a “quirky classic,” reflective of Brooks’s original and idiosyncratic approach to the field of project management (Lohr, Steve. “Frederick P. Brooks Jr., Computer Design Innovator, Dies at 91.” The New York Times, 23 Nov. 2022).
