I only saw Mrs. Furlan in person once, at San Diego, just as Babylon 5 was getting going. And that, from across a standing-room only hall. Her work on-screen was nonetheless stellar, in the best sense, in the role of Delenn.
I never got to see Mr. Aaron, but I read the Peanuts strip with Snoopy standing in for Mr. Aaron, taking his own share of hate mail as a fictional beagle on his own quest to break Babe Ruth's record, and later learned the fuller story. Mr. Schulz was clearly a fan of Mr. Aaron, from what I saw in print.
Two people worthy of respect. Now both gone.
