Henry joined SCA this month and will work one day a week in the paid position, overseeing creative work and mentoring students.
Speaking about Henry’s arrival, Marc Lewis, the dean of SCA, said the position was an expansion of Henry’s existing role: "Steve was already mentoring ad-hoc, visiting the school a couple of times each term.
"He still has that incredible drive to produce game-changing ideas that led him to winning everything in his career and I saw how well the students all responded to his philosophies. It’s contagious.
"We want to be known as the best school in the world. We are hungrier that Vanessa Feltz on Yom Kippur and I think that’s why Steve enjoys hanging out with us."
Henry, who will continue his work at Decoded, added: "I’ve always loved SCA, it feels very vibrant and challenging. I’m drawn to mould-breaking thinking, and you get that with a lot of their students.
"I’m incredibly busy right now, but I’m looking forward to working two or three days a month with them, finding and developing revolutionary ideas, not just for advertising, but for business as a whole."
