View from the barrier

Cold and horrid yesterday and the nearest I got to the Royal Docks Campus was looking at the river from the barrier site. There was a ship at the Tate and Lyle jetty - 'Ismail K' . Does anyone know any more about it?- and being at the barrier brings me to Siemens - the electrical engineering giant whose factory was in that area until the 1950s. Some one emailed me the other day asking for information on Siemens records. She is a family history researcher looking for info about her grandfather who , she says, hung himself at Siemens Cable works in 1929. She is wondering if there are any personal records of such things.
