Sir Roy came to prominence at age 32 when he became the youngest director of the National Portrait Gallery. He set about transforming its conservative image with a series of extrovert shows, including 600 Cecil Beaton portraits.

Dedicated to the culture of the 60s and 70s, Sir Roy went on to wow audiences at the V&A in 1974 with his collection of fedora hats, kipper ties and maxi coats. By regularly introducing new exhibitions he doubled attendance.
