Susie: My husband is a great handyman. He can repair almost anything.
Jane: My mother always taught me to beware of the man that can fix everything. You'll never get anything new.
Jakob Christof Le BlonDied 16 May 1741 at age 73 (baptized 23 May 1667).German-French inventor who invented the modern system of four-colour printing. Influenced by Newton's work on the light spectrum, after many printing trials, Le Blon in 1710 proposed that three primary colours - cyan, magenta and yellow (blue, red, yellow) and black - are sufficient for mixing in varying proportions to produce all other colours. He used this process to print engravings that mimic the full colour of paintings by superimposing mezzotint plates in each primary colour. For each hand-engraved plate, the individual contribution of each colour estimated. In 1719, George I granted him a priviledge of a monopoly for the reproduction of pictures and drawings in full colour. Nevertheless, by 1725, his company failed.«[Also spelled Jacob Christoph Le Blon; in French as French Jacques-Christophe Le Blond.] |
