Fascinating facts about the invention of Erector Sets by A.C. Gilbert in 1913. ERECTOR SET
Born in Salem, Oregon in 1884. A. C. Gilbert (1884-1962), boyhood love was magic tricks: he became so proficient that he once matched a traveling professional magician trick for trick, and earned the prescient praise, Gilbert was also a brilliant student, and soon went on to Yale Medical School. He helped pay his tuition by performing as a magician, and founded a company, Mysto Manufacturing, which sold magic kits for kids. In 1909, Gilbert finished medical school, but decided to expand his budding toy business rather than practice as a doctor.
Like many residents of New Haven, Connecticut, he often took the train to New York City; and on one trip in 1911 he was inspired with what would be the most popular of his dozens of inventions.

Watching out the train window as some workmen positioned and riveted the steel beams of an electrical power-line tower, Gilbert decided to create a children's construction kit: not just a toy, but an assemblage of metal beams with evenly spaced holes for bolts to pass through, screws, bolts, pulleys, gears and eventually even engines. A British toy company called Meccano Company was then selling a similar kit, but Gilbert's Erector set was more realistic and had a number of technical advantages --- most notably, steel beams that were not flat but bent lengthwise at a 90-degree angle, so that four of them nested side-to-side formed a very sturdy, square, hollow support beam.

Gilbert began selling the "Mysto Erector Structural Steel Builder" in 1913, backed by the first major American ad campaign for a toy. The Erector set quickly became one of the most popular toys of all time: living rooms across the country were transformed into miniature metropoles, filled with skyscrapers, bridges and railways. Those kids who already owned a set would beg Santa annually for an upgrade, aiming for the elusive "No. 12 1/2" deluxe kit that came with blueprints for the "Mysterious Walking Giant" robot. It is difficult for anyone under the age of 35 today to appreciate just how popular the Erector set was for over half a century.

A. C. Gilbert was one of the most multi-talented inventors of all time. With many fields open to his ingenuity, he chose to educate and entertain children through toys.
