Friction match patent

In 1836, Alonzo Dwight Phillips of Springfield, Massachusetts, received the first U.S. patent for the phosphorous friction safety match (No. 68). The first friction matches, using a mixture of chemicals for their heads, were made and sold in England in 1827. Phillips' match, which could be struck on any rough surface, was the first genuine friction match made in America. Known as “loco focos,” and later as “lucifers,” these matches were made entirely by hand from a mixture of chalk, phosphorus, glue and brimstone (sulphur). The introduction of gas for lighting and cooking, and the spread of cigar smoking, made the lucifer almost a necessity. By the time of the Civil War, about a million matches a day were being manufactured.
