I added this new information to his entry here: https://imslp.org/wiki/Category:Jackson,_Arthur
This included his birth and death dates, nationality (he was born and died in the USA so assume he is a US citizen) and also included the photo of him from his obituary.
In the interest of transparency, below are links to the sites where I took this information:
https://www.ancestry.co.uk/genealogy/re ... -24-l5mx2v
https://peoplelegacy.com/arthur_james_jackson-634X59
Gravestone information:

Obituary in the Jewish Criterion Vol. 58 No. 16, p.14

Article on Wordpress with more biographical information:

BUT now I realise he has 2 entries on the IMSLP site as this category is also him: https://imslp.org/wiki/Category:Jackson,_Arthur_J.
How can these two entries be merged, please?
