Need help - right word for honoring deceased official

Someone on my organization’s advisory council has just passed away. Rather than remove his name from our stationery and website, we’d like to keep it there for the remainder of his term but indicate that he has passed on. I know there is a proper way to do that, but I’m blanking on the correct term. Is it “in memoriam”?

The Latin phrase in memoriam means “in memory of” but that may not be want you want to say.

This looks like a pretty good resource:

It agreed with my first instinct – to print it as:

John Q. Smith (1935 - 2021)

Thanks! I would never have thought of putting the years of his life after his name, but it seems like a good option.

Over here, I’ve seen a dagger or obelus symbol used to indicate someone deceased.
