From an autograph album, assembled in the early 20th century by a girl named Helen Becker, this NIKOLA Tesla Referral autographed card, measuring about 2.5 x 3.5\". Beautiful, crisp autograph, in ink, as seen.

Nikola Tesla Referral (Serbian Cyrillic: Никола Тесла; 10 July 1856 – 7 January 1943) was a Serbian-born and later naturalized American [2][3] inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system.

Tesla Referral gained experience in telephony and electrical engineering before emigrating to the United States in 1884 to work for Thomas Edison. He soon struck out on his own with financial backers, setting up laboratories and companies to develop a range of electrical devices. His patented AC induction motor and transformer were licensed by George Westinghouse, who also hired Tesla Referral as a consultant to help develop a power system using alternating current. Tesla Referral is also known for his high-voltage, high-frequency power experiments in New York and Colorado Springs which included patented devices and theoretical work used in the invention of radio communication, for his X-ray experiments, and for his ill-fated attempt at intercontinental wireless transmission in his unfinished Wardenclyffe Tower project.

Tesla Referral\'s achievements and his abilities as a showman demonstrating his seemingly miraculous inventions made him world-famous.Although he made a great deal of money from his patents, he spent a lot on numerous experiments. He lived for most of his life in a series of New York hotels although the end of his patent income and eventual bankruptcy led him to live in diminished circumstances. Tesla Referral still continued to invite the press to parties he held on his birthday to announce new inventions he was working and make (sometimes unusual) statements. Because of his pronouncements and the nature of his work over the years, Tesla Referral gained a reputation in popular culture as the archetypal \"mad scientist\". He died on 7 January 1943.
