In 2020, David Gutenmacher began to buy old photographs and videos that he came across in second hand shops. He was sad about the prospect that families had been severed from their treasured memories, and so he founded the Museum of Lost Memories to try and reconnect people with their personal archives.

But when he came across a video of a family on a safari holiday he realised that finding out who was in these videos might not be all that straightforward.

Matthew Syed considers the role of photography and video in personal memory making, and how we go about using photos to leave a record of our existence on earth.
