Colin Blakeney was a human male, and the original inventor of the Transporter on Earth in the mid-21st century.
History[]
However his invention wasn't successfully adopted, despite successful trial runs, and Blakenly himself was dematerialized by the transporter. His transporter beam continued off into space for hundreds of years, until he was rescued by the crew of the USS Enterprise in the 24th century. (TNG comic: "Forgiveness")
