In May, the iconic hairstylist Vidal Sassoon passed away at 84 years old. In celebration of his life and revolutionary career, a memorial service was held this past Friday where family, friends and celebrities from the fashion, film and art industries gathered in his honor. Sassoon’s stone urn was designed by friend and sculptor Anish Kapoor who said, “Vidal was always mad about architecture”—how fitting, then, that his memorial was held at the exquisite St. Paul’s Cathedral in London.

“On a professional level I don’t think there is anyone in our industry that has achieved what he achieved. He was a man that completely revolutionised the industry in a way no one else ever has,” said professional hairstylist John Freida before the crowd. Sassoon transformed the hairstyling industry with geometric cuts and styles that freed women from the high maintenance of large beehives and chignons.

Sassoon is survived by three children and his fourth wife Ronnie.
