He came up with the idea in 1902, suggesting it to the English Parliament as a way to prevent people "wasting daylight".
He suggested moving clocks backwards by 20 minutes every Sunday in September. Despite having the support of author Sir Arthur Conan Doyle as well as Winston Churchill, his idea was rejected by the government of the time.
It was the Germans and Austrians who finally introduced daylight saving in 1916, but it wasn't to stop people wasting daylight or to increase bug collections then.
It was introduced by the two nationalities to save candles and coal power, extending the working day as part of their war effort. They had the idea from Willett's much publicised campaigning in England and made it a reality.
Soon after, Britain, America and other countries involved in World War I followed suit, and in the United States daylight saving was originally known as "war-time" as a result.
Daylight saving was then finally introduced in New Zealand in 1927, 32 years after Hudson first suggested it.
So this weekend, when you get a whole extra hour in bed on Sunday morning, just remember, it is all thanks to a bug obsessed New Zealander.
