About William Hudson (engineer)
Sir William Hudson was a New Zealand-born engineer who headed construction of the Snowy Mountains Scheme for hydroelectricity and irrigation in Australia from 1949 to 1967, when he reluctantly retired at 71. The scheme was completed in 1974, under budget and before time. He was elected in March 1964 a Fellow of the Royal Society, and was awarded the James Cook Medal of the Royal Society of New South Wales in 1966. During his time studying in London, he visited the site of an early attempt to put a tunnel under the river Severn, an endeavour undertaken by his ancestor William Fendall among others.
