World-changing inventions including penicillin, television, the miniskirt and daily newspapers were all invented in London.

Richard Happer's new book 365 Reasons to be Proud to be a Londoner shows us why we shave a reason to celebrate our great capital every day of the year.

Here are a few:

On March 17, 1918 book Married Love by UCL academic Marie Stopes was published. Condemed by some as obscene because it had the audacity to educate women about birth control it was in its sixth printing within a fortnight and the author later opened the Mothers' Clinic in Holloway.

On April 8, 1891 dog-mad chap Charles Cruft decided to hold a parade of pooches at the Royal Agricultural Hall, Islington and the world's largest annual dog show was born.

On November 17, 1895 the first batch of Lee-Enfield .303 military bolt-action rifles were produced in Enfield.

On December 21, 1966 a special act of Parliament established London largest park. No not Hyde or Regents but the 10,000 acre Lee Valley Park.

DISCOVER hidden nooks and crannies with new guide book Crouch End - Four Walks.

Written by local historian Eleri Rowlands and published by Hornsey Historical Society it will tour you on a quartet of rambles all starting and ending at the clocktower.

The 30-page book suggests four routes, centred around Park Road, Weston Park, Crouch Hill and Crouch End Hill, which are short enough to be completed in a couple of hours, accompanied by a colour coded map and photographs, some taken especially by Lesley Ramm and some from the society archives, which highlight key buildings and landmarks.

It replaces the society's previous book Crouch End Walk written by Ken Gay who died earlier this year, which was published in 1995.

Since then much has changed and the new book takes in the old and new with snippets such as the fact Tottenham Lane's Art House Cinema used to be a Salvation Army Citadel and in 1845, Haringey Park was the first road to be laid out in Crouch End since medieval times.

The book priced £4.50 is on sale now at Hornsey Historical Society, The Old Schoolhouse, Tottenham Lane, Crouch End.
