My paternal grandfather, William Ernest Easter, worked at the gas works in Wimbledon in London. Here he is, ready with his spanner. I’m not sure what date this is, but he’s probably about 25 or 30, which would make it about 1913 or so.
My father remembers one of his first jobs on leaving school was to polish the brass fittings in the same gas works. Later in life my grandfather left the gas works and became a boot maker and repairer – a family trade.
