When you walked out of ALDGATE EAST tube station in 1950, like today, it would have been quite busy during the day and in late evening. As you walked towards your destination you would have passed certain land marks, such as a fire station, police station ? Did you notice lots of shops? (who's window would have some form of lighting) Did you pass mainly office buildings ? (therefore the street would have been much darker, as you seem to suggest in your post).
When you got to Stepney, did you take another short underground rail journey ? The reason why I ask this is because just over the river was a large docks complex, part was large areas known as Surry Docks. The rather smaller collection of docks were known as the Commercial Dock Co, however that was up to 1865, in that year they were merged to become the Surrey Commercial Docks. Having said this, I know they were often referred to as the Commercial ( or Commi) Docks.
The East End has changed an awful lot, people who look for an area called Limehouse, discover that the rail station there, along with the DLR station are called Limehouse, but in truth it's real name was East Stepney, and true Limehouse is more than half a mile down the road. For this reason I am seeking what ever memories from your walking through the East End that may help.

P.S.- I do not visit this site every day.
