I live a couple of miles from where they tested the bouncing bombs. The town of Herne Bay has a statue to the great man who really should have got more credit for his ideas. The invention I like most is the tallboy bomb (and the Grand Slam).
This extract from the wiki I think sums the man up...
He was awarded the sum of £10,000 for his war work from the Royal Commission on Awards to Inventors. His grief at the loss of so many airmen in the dams raid was such that Wallis donated the entire sum to Christ’s Hospital School in 1951 to allow them to set up the RAF Foundationers’ Trust, allowing the children of RAF personnel killed or injured in action to attend the school.
