Charles Constantine Collins (aka Sir Collins), was a Hackney-based music producer, businessman, campaigner, community organiser and citizen-archivist who arrived in London from Jamaica in 1957 and lived in Hackney, East London, for over 50 years. Throughout his long and enterprising life, Sir Collins remained focused on documenting the social and cultural journey that African-Caribbean people have made in the UK through film, photograph, text and song. He knew the power of history and understood the need for people to have their activities and achievements preserved for future generations. Sir Collins created a large and detailed collection of papers and audiovisual material during his lifetime. This collection spans the period from his arrival in the UK to his passing in 2018. The records stored in the numerous boxes deposited at Hackney Archives includes material charting the development of Reggae music in the UK and internationally; the foundation and development of the Four-Aces Club in Dalston, Hackney; grass-roots community initiatives, campaigns and protests in Hackney and further afield; police liaison and scrutiny work to improve community policing in London; documentation concerning the aftermath of the New Cross Fire and public-realm memorialisation connected to the tragedy.
