William Willett was a builder and in 1907 financed and wrote his own pamphlet titled 'The Waste of daylight'
He argued and campaigned for an advancement of 80 minutes in the summer time and a reduction of the time during Autumn.
In doing this, evening times would become lighter and more enjoyable/productive for everyone. Energy costs would be greatly reduced and he claimed that this change would benefit the health of the nation.
'British Summer time' become law in 1972.
Britain and the rest of Europe (excluduing Iceland) abide by the 'Daylight saving time' directive.
Unfortunately William died in 1915 - at 58 years of age and whilst he never saw his British summer time come into effect 'The William Willett commemerative memorial sundial' erected near Petts wood in Kent, is set to continual Daylight saving time in his honour. You can See the dial
