How would you go about contacting the owner of a dormant wallet?

I am doing a report on cryptocurrency and been doing some research on the early days, I've been looking at a list of dormant wallets over 8-10+ years. I understand that a main aspect of cryptocurrency back then was privacy but say I wanted to speak with someone who owns one of these wallets from the early days and ask a few questions for my report specifically about leaving their coins untouched, where they believe Bitcoin is going, how did they got into the space etc is there a route to contact them?

I'm not fully up to speed but say if I was to transfer a small amount of BTC to a wallet can you get a message to them that way if they still have access? I've done the usual thing like searching an address and seeing if anyone has mentioned owning it etc etc but there are lots and the person may never respond so it might be a completely fruitless endeavour from an overreaching student however I thought I would ask the community here for advice before leaving that idea behind.

Thanks in advance
