John T. Hayward
T. Hayward began his oil industry career in Europe in 1913 where at the
age of 23, he was a tool pusher on the first rotary-drilled oil well in
Europe. He was primarily an engineer and inventor and spent much of his

and worked successfully until retired in 1968.

Laborde on the design of the Mr. Charlie, the world's first open water
