The Austrian sits very firmly in the pantheon of F1 greats. One of the best, not just of his generation, but of all time.
On and off the track, he built a legacy few will replicate in F1 folklore. In the paddock as a driver, he was revered. In his later years on the other side of the pit wall, he was everyone's friend.
Simply put, wherever Niki went, he left a mark and made a difference.
"One of my favourite memories of Niki was in Brazil," recalls Lewis.
"Myself, Niki, and Toto had gone for Sushi. Niki dropped some fish and it landed in some soy sauce and splattered all over him.
"We all just burst out laughing, and that is what is was all about. It was not business, just three guys laughing really hard!"
George also quickly felt the warmth and friendship of Niki on joining the team.
"My first race with the team was Baku in 2017. I had only been part of the team a couple of months, but Niki came straight up to me and welcomed me with open arms," he said.
"He invited me to a concert that evening, and we just danced the night away and had such a great time. There were so many laughs along the way.
"Experiencing something like that with someone you looked up to as a kid was so surreal.
"He was such a kind person, so down to earth. He just enjoyed doing the things in life that we all enjoy doing."
