Leslie R. Mitchell

Lore & Background

Mitchell was born in Hammersmith, the only child of Horace Richard Mitchell, a civil servant, and Amy Lily Staple. His father's work managing labour exchanges moved the family around England, eventually settling in Reading, where Mitchell joined the Sea Scouts. During World War II he served in the Royal Navy as a radio mechanic, posted in the United States and Australia, where he volunteered as a Scout leader. After the war he used his radio skills to obtain an amateur transmitting licence and joined the civil service, working at government science research facilities at Winfrith in Dorset and Datchet in Berkshire, managing transport arrangements.

Mitchell tried for years to interest Scouts in amateur radio without success until the 9th World Scout Jamboree at Sutton Park in 1957, where the first amateur radio station in a Jamboree area was set up under call sign GB3SP. Scouts could only observe, but Mitchell met many Scout radio operators there. They agreed to contact each other on a specific day, which Mitchell arranged. He expanded that day to a weekend and invited other operators to open their stations to local Scouts. In October 1957 he set up a 40-watt AM transmitter in a tent outside his Scout Group's hall in Reading, and Scouts made contacts worldwide. With permission from the radio licensing authority and The Scout Association, and a set of simple rules still in use, the first JOTA followed in May 1958, then annually in October. Mitchell gained support from the World Scout Bureau.

As JOTA grew, Mitchell gave the opening address at the first Radio Scouting Conference in Lillehammer, Norway, during the 14th World Scout Jamboree in 1975. He was awarded the Bronze Wolf in 1978. The 40th JOTA in 1997 was operated from the 79th Reading Scout HQ with Mitchell transmitting. In later life he became a family historian and speaker. He participated in JOTA until within a few years of his death. He died shortly before JOTA 2014; a one-minute silence was observed during the event, which had 1,332,265 participants from 157 countries. His funeral was held at St Peter's Parish Church, Rawdon near Leeds, with World Scout Bureau advisor Richard Middelkoop attending.

Reader's Guide

Mitchell's creation of Jamboree-on-the-Air established a lasting bridge between amateur radio and Scouting, growing from a single tent experiment in Reading to the largest scheduled event of the World Organization of the Scout Movement. The event's simple rules, drawn up by Mitchell, have remained in use since 1958. His work demonstrated how radio could connect Scouts across borders, and the annual October event continues to involve hundreds of thousands of participants worldwide. Mitchell's own involvement spanned decades, and his legacy is reflected in the event's endurance and scale. The 2014 JOTA, held just after his death, saw over 1.3 million Scouts and Guides from 157 countries take part, with a moment of silence observed in his honor. The Bronze Wolf Award, Scouting's highest distinction, recognized his exceptional service. Mitchell's approach—combining technical skill with volunteer leadership—shaped a global tradition that remains central to Radio Scouting.
