Have you ever had to draw a series of parallel lines or hatches on a drawing and got bored? Fred’s first job was working as a draughtsman in a patent agent’s office and experienced the same sense of dullness at this mundane, boring and repetitive role. He set to work thinking of an invention that could save time and invented the Isometrograph which he patented in November 1888 when he was just 20. The original patent can be found online here.
