He was something of an inventor, but was not averse to using the ideas of others without giving due credit. He probably effected improvements to others' inventions by applying rigorous scientific principles. However, generations of historians have learned not to take his statements at face value.
L. T. C. Rolt described him as belonging to 'that scientific school which refused to credit that a practical man without scientific training could achieve anything except by chance and good luck.'
