1910’s: London Polytechnic Water Polo Club

The team of “London Polytechnic Water Polo Club” about 1910’s. The 'Poly' was formed in 1874, as part of the then huge Polytechnic of Central London Institute, who can boast among their achievements the staging of the 1920 Olympics at White City. (The Olympic pool at the City University site was still used by the Poly for training until two years ago when, sadly, the roof fell in!).
