work in precision mechanical horology. In 2009 he received the Institute of Electrical and Electronics Engineers (IEEE), Dennis J. Picard Medal for Radar Technologies and Applications: "for pioneering work of fundamental importance in radar waveform design, including the Woodward ambiguity function, the standard tool for waveform and matched filter analysis". Achievements in horology In retirement, Woodward wrote another classic book, My Own Right Time fondly known as MORT, a record of his passion for horology. Along with many other topics, MORT describes in detail the design of his clocks, including his masterpiece W5. Woodward contributed dozens of articles to horological periodicals over more than 30 years. From his experience as a mathematician and analyst of complex systems, he has made major contributions to scientific horology, including the definitive analysis of balance springs and much work on the properties of pendulums. In 2006 the British Horological Institute published a hard-cover collection of 63 articles with new notes by Dr. Woodward. The collection, Woodward on Time, originally compiled by Bill Taylor, ASC. became instantly known as WOT. It was very well received. W5 clock W5 was built in a small workshop with the simplest of tools, but displays an elegance of concept and design rarely seen in the history of the science. It was acclaimed by Jonathan Betts, the Senior Curator of Horology at the Royal Observatory, Greenwich as "the nearest approach to perfection by any mechanical timekeeper not employing a vacuum chamber". Woodward built even the case, assembling it with intricate but invisible hidden mitre joints. The eminent horologist Anthony Randall carried on a long series of timekeeping trials of W5, showing unprecedented accuracy over periods of more than 100 days. Although the clock was widely celebrated, and Dr. Woodward published a series of ever-more-detailed articles on its construction to encourage others to carry its ideas forward, no one completed another clock like it for more than twenty years. Finally, in 2006, the Australian clockmaker David Walter (now of Buellton, California) succeeded in making a highly skeletonized version that while quite different in details, closely followed the basic Woodward design. Personal Woodward was born on 6 September 1919 and educated at Blundell's School in Tiverton, Devon. He met his wife, mathematician Alice Mary Winter Robertson (1917-1999) whilst they shared an office in Durnford House in Langton Matravers as part of the Telecommunications Research Establishment. She detailed the field solution for a
