In West Orange, New Jersey on February 1, 1893 Edison finished construction of "Black Maria", the first motion picture studio. However, a United States court of appeals ruled on March 10, 1902 that Edison did not invent the movie camera and thus could not exercise monopoly power over its use (see Edison v. American Mutoscope ). In 1894, Edison experiments with synchronizing audio with film; the Kinetophone was invented which loosely synchronizes a Kinetoscope image with a cylinder phonograph. In April of 1896, Edison and Thomas Armat's Vitascope were used to project motion pictures in public screenings in New York City.
Thomas Edison submitted his last patent application, "Holder for Article to be Electroplated", on January 6, 1931 and died later that year. The patent was granted two years later in 1933.
He was married twice, the first time in 1871 to Mary Stilwell ( 1855- 1884), with whom he had three children - Marion Estelle, Thomas Jr., and William Leslie - before she died at age 29, probably of typhoid fever. His second marriage was to Mina Miller ( 1865- 1946), also with three children, Madeleine , Charles (who took over the company), and Theodore Miller . Thomas Edison was an atheist.

The town of Edison, New Jersey, and Thomas Edison State College, a nationally-known college for adult learners in Trenton, New Jersey, are named for the inventor. There is a Thomas Alva Edison Memorial Tower and Museum in the town of Edison.
