In this position, Colburn made friends with members of the Institutions of Civil and Mechanical Engineers and became a member of both. He gave frequent lectures and contributed at meetings. It is almost certain that while in London Colburn met Isambard Kingdom Brunel. In 1860, Colburn returned to America on the maiden voyage of the "Great Eastern", Brunel's leviathan steamship. In America he launched a new weekly engineering newspaper, "The Engineer", but this lasted only a few months and Colburn returned to England
