It doesn't actually say who created the actual Morse code, but it seems that " A related but different code was originally created for Samuel F. B. Morse's electric telegraph by Alfred Vail in the early 1840s. This code was the forerunner on which modern International Morse code is based. In the 1890s it began to be extensively used for early radio communication before it was possible to transmit voice. In the late nineteenth and early twentieth century, most high-speed international communication used Morse code on telegraph lines, undersea cables and radio circuits."
