Watching my wife vacuum the living-room at the weekend, using a Dyson, it occured to me that makers of vacuum cleaner bags are either already redundant or soon will be. I should add here that I may well have wielded the Dyson myself but am convalescing after an op. I then recalled that the first job my mom had after leaving school in the '30's was as a colourist in a photo studio. Her job was to paint in the colours on black & white photos! The photographer would write what the colours should be, and my mom would try to match the colour in paint. With the advent of colour photos, she of course lost her job. She then became a bus conductor or 'clippie' - although strictly speaking a tram conductor, as these were still in use in Manchester during the '40's and a bit later. This is another recently defunct profession - conductors were certainly still around when I used buses in the '60's and early '70's (move down the bus!) so not sure when they were phased out but they're not there now. After that, my mom worked in a woollen mill as a loom operator, and now they're all gone! Maybe it's something to do with my mom, but there must be a load of jobs that have, or soon will be, consigned to history and memory.
