Did Diemschutz use different spellings of his name or did other people just mis-spell it?
It's a name of Russian origin, where the "real" spelling would be ДЫМШИЦ, but which could be transliterated into the Latin alphabet in a number of different ways - just like Чайко́вский, which is rendered as Tchaikovksy, Tschaikowsky, Tchaikowskij, Tsjaikovski, Czajkowski (etc) depending on who you ask and where you are.
So, you could argue that there's no "correct" spelling for ДЫМШИЦ, except in is native Cyrillic form. Everything else is a compromise.
I just find it difficult to believe that Jack the Ripper would commit a murder on his way to work?
a) he wouldn't have risked turning up for work spattered in blood (no matter how small an amount) when a murder had occurred on the very route that he'd taken to work.
b) he couldn't have known how long the murder would take to commit and we know how pushed for time he was. His main thought was not being late for work.
c) surely he took the same route to work every day and so it's likely that he'd seen Robert Paul before even if they'd never spoken. So if he knew that at least one other bloke walked along the same street at around the same time every day it would have deterred him.
d) I think that we would all think it was unlikely that Richardson would have killed Annie Chapman in his mother's back yard. Or that Reeve would have killed Tabram on a landing in the building where he lived. We don't know how intelligent Jack was but we can, at least, say that he was smart enough to avoid detection; would he really risk murdering a woman in a spot that he past every day on the way to work.
e) if he was guilty surely he'd more likely have just run when he heard Paul's footsteps around 40 yards away( a good head start )
f) he gave the police the name he used in speech every day. If he'd have called himself Lechmere people would be saying why didn't he use the name that he used every day (Cross)
g) he turned up to the inquest and gave a completely plausible account of his actions.
I, personally, can't see him as the ripper. I think the name thing has added mystery where none really exists.
That just about sums it up. I agree that he's another very weak candidate .
