Here is a lovely article about Irvin Faust sensei called "Most Influential Person" written by Nahjiim Engram in 2019 when Nahjim was a teenager: http://usafaikidonews.com/most-influential-person/
From the article: "My mentor is Sensei Faust who is my Aikido teacher. He is a 7th Dan black belt (Shihan), and he is one of the top ranked people in the world. He is also the very top ranked African-American Aikidoist in the United States Aikido Federation. He even holds rank in Karate, Kung Fu, and Tae Kwon Do. He has trained and taught here and in Japan. He teaches in clubs at RPI, he teaches home-schoolers, and he teaches at youth charities. He is also a veteran. He has inspired me by being the most accomplished person I know and made me want to try to get a rank higher than his and learn as much as I can."
