Alexander Hastie Millar, Dictionary of National Biography (1901)
“ In a letter to the 'Northern Warder,' a Dundee newspaper, on 26 June 1845, Lindsay proposed a transatlantic telegraph, by means of uninsulated copper wire, and suggested that the wire joints might be welded by electricity. In 1853 he announced, in a lecture on telegraphy delivered in Dundee on 15 March, that by establishing a battery on one side of the Atlantic and a receiver on the other, a current could be passed through the ocean to America without wires. ”
