Who invented the chalkboard eraser?

Answer 1

While researching for my daughters school project we after much searching came up with this information. The answer is........ JL Hammett. The history of J.L. Hammett can be traced back to 1863. Rhode Islander John L. Hammett was a http://www.answers.com/topic/schoolteacher who had authored grammar books and worked as a representative of a publishing house, all roles that developed his sensitivity to the needs of educators, tapped his potential as an innovator, and developed his business sense. In 1863 he established a small school-supply shop in Rhode Island and, two years later, moved it to a single store location in Boston, Massachusetts. Hammett was an inventor as well, having developed a "slating paint" which could be applied to the slates children used in school, prolonging the life of the boards. The paint could also be used to turn a wall into a http://www.answers.com/topic/blackboard. Furthermore, Hammett invented the chalkboard http://www.answers.com/topic/eraser: during a presentation, when he could not find a cloth to http://www.answers.com/topic/wipe his slate, he picked up a http://www.answers.com/topic/carpet remnant and discovered that it cleaned the slate much better than the cloths he had been using. With the help of his assistant, Hammett began to http://www.answers.com/topic/nail pieces of carpet to blocks of wood which were then sold as erasers. Invention and manufacture was a concern of the company from its inception until the 1950s, as the company would make ruled paper, mix ink, and manufacture various other school products. By the end of the 19th century, increased production made paper more affordable and accessible for schools and teachers, and the demand for slates and related products diminished. In 1890 Hammett sold his business interests to a new generation of owners composed of Massachusetts investors led by Harry H. Young.
