Peter Pyhrr

Peter Pyhrr is an American business writer. He was a manager at Texas Instruments in Dallas, Texas, who developed the idea of zero-based budgeting. He used ZBB successfully at Texas Instruments in the 1960s and authored an influential 1970 article in Harvard [Business Review]. In 1973, President Jimmy Carter, while governor of Georgia, contracted with Pyhrr to implement a ZBB system for the State of Georgia executive budget process.
Called 'the father of Zero-Based Budgeting', he reportedly "sent an article about the technique to Harvard Business Review and was surprised when they ran it — and even more surprised when he got a call from a staffer for Jimmy Carter, then Democratic governor of Georgia."
Pyhrr was age 27 when he developed ZBB at TI.
