Albert Augustine Ltd.

Albert Augustine Ltd. is the originator of and currently a manufacturer of nylon classical guitar strings. In addition, the company supports the classical guitar and guitarists by presenting several annual New York guitar series at the Manhattan School of Music, the Queen Sofia Spanish Institute and other important venues, by commissioning hundreds of original solo and chamber music works and concertos from some of the foremost contemporary composers, by donating thousands of dollars for scholarships, special artist's projects and guitar festivals, and by publishing Guitar Review magazine.

In 1926-7, Albert Augustine (born Denmark 1900, died New York City, April, 1967) moved to the United States to pursue his career as a luthier. In 1928, he married his wife, Rose.

During this period, he experimented with different types of strings without significant result. It was to be almost 20 years before his collaboration with famed guitarist Andrés Segovia would result in the development of the nylon guitar string.

In the mid-1940s, Andrés Segovia mentioned the shortage of good guitar strings in the United States, particularly his favorite Pirastro catgut strings, to a number of foreign diplomats at a party, including General Lindeman of the British Embassy. A month later, the General presented Segovia with some nylon strings which he had obtained via some members of the DuPont family. Segovia found that although the strings produced a clear sound, they had a faint metallic timbre which he hoped could be eliminated.
