I had the great pleasure of spending an hour in the company of Kenneth Grange at The Lightbox in Woking. The talk lasted a little over an hour but Kenneth could have talked, and we would all have listened, for days. Among his many anecdotes was the story of how his prototype model for the Kenwood Chef was unfinished 3.5 days into his allotted 4 days. He sliced the model in half, length ways, and took a mirror to the pitch. Ken Wood was so taken with the presentation and perfect symmetry that Grange was hired and they never looked back.
If you ever have the opportunity to attend a talk with Kenneth Grange I implore you to go, you'll hear about opening Swiss offices to aid skiing holidays, how the Ferrari Daytona has influenced all car design and how all packet food is designed to be made with only a fork.
