Robert H. Marriott (19 February 1879 - 31 October 1951) was an electrical engineer who is intimately associated with the birth of the radio age. Marriott began studying radio (then known as "wireless") in 1897 at Ohio State University. He graduated from that institution in 1901 with a Bachelor of Science degree. From that point until his death in 1951, he was a tireless developer of radio technology. He played a vital role in developing the Ambrose Channel pilot cable for the Navy and developed many other technologies. Marriott was a founding member of what is today known as IEEE. He planned and installed the first civilian AM radio broadcasting equipment in the United States.
