(UPDATED 11/14/21: His death has since been confirmed and even his Wikipedia page has been edited.)
Apparently, the voice actor, Val Bettin, has sadly passed away at the age of 97. I say “apparently” because no news stories picked up his passing even though it happened on January 7, 2021. The only evidences that seem to confirm his passing are his Star Tiger page and his FindAGrave page.
Mr. Bettin (1923-2021) most famously provided the voice of Dr. Dawson in Disney’s The Great Mouse Detective as well as the voice of the Sultan in Disney’s Aladdin sequels and television series. He shall be missed!

As man, I had no idea he was still around. RIP Dawson & Sultan.
Yeah, it’s sad. I hope news sources will pick this news up though.
You can remove the word “apparently”.
Go to https://www.ivylawn.org/find-loved-one/ and search under surname “Bettin”, the full record comes up with his full name, birth date, death date, burial date and a picture of the gravestone. Confirms it. Very sad, RIP.
Thanks! I also see that his Wikipedia page has been updated too.
Why did you delete my comment? I was trying to help you. Very rude!

I didn’t realise this had happened till today; he’s been gone a year, poor guy! RIP Mr Bettin
