Leonard Ambrose Cundell (born Berkshire, England, 1879, died Blewburton Hall, Aston Tirrold, Berkshire, England 15, December 1939) was a well known British racehorse trainer in the 1930s. He was the second son of farmer and butcher Matthew Henry Cundell and Emma Willis of Coley Park farm, near Reading.
He had stables at Chilton in Oxfordshire which were taken over, by compulsory purchase, by the British government about 1937 in order to build RAF Harwell.
A stone marking the end of the runway records that aircraft of No 38 Group RAF took off on the night of the 5th of June 1944 with troops of the 6th Airborne Division who were the first British soldiers to land in Normandy in the main assault for the liberation of Europe. After World War II RAF Harwell was taken over by the UK Atomic Energy Authority.
Len Cundell moved from the Bungalow stables at Chilton to Blewburton Hall stables at Aston Tirrold. His best horse was Noble Star who, as a four-year-old, won the Cesarewitch in 1931.
His cousins Ken Cundell and Frank Cundell, and his nephew Jack Waugh, the son of Len's sister Letitia, also became successful racehorse trainers and gained experience in his yard. Ken Cundell was one of the first to recognise Lester Piggot's outstanding talents
The racehorses could not be kept following the outbreak of World War II. Some were given away to local farmers to ride while others had to be shot. Len died suddenly just before Christmas 1939.
