Danter worked as an engine smith.[1] He came to prominence in the Amalgamated Society of Engineers (ASE), where he served as chairman of the executive in the 1860s.[2] He became associated with the "Junta", an informal council of leading trade unionists,[1] and was also elected as chairman of the London Trades Council.[2]
By 1868, Danter had been replaced as chair of the ASE by W. Robson.[1] In 1872, he and Charles Temple were awarded a patent for "an improved union, joint or coupling for hose and other pipes".[3]
