Shortly after the first revelation, he was identified as 29-year-old Saudi billionaire Hassan Jameel.
His wealth came from the textile business, but on both sides of his family there were connections with the arts and traditions of patronage going back several generations.
Courtauld loved pictures and wrote poems about them.
His first collection of pictures, not a great success, was donated to the nation along with Chequers; but his later efforts were more discerning, and went hand in hand with his scheme for a specialist institute, first mooted in 1927.
If Lee knew how and where to exercise influence, it was Courtauld who provided the bulk of the money.
He was seen canoodling with British model and actress Naomi Campbell in 2016.
Ms Campbell and the “Umbrella” songstress have a history of drama, with the pair famously unfollowing each other on Instagram last year.
The billionaire's group also has partnerships with the Massachusetts Institute of Technology, Victoria and Albert Museum in London, and the Grameen Foundation.
Riri also has her own charitable organisation called the Clara Lionel Foundation that focuses on global health and emergency response.
Samuel Courtauld was the real Maecenas of the trio, and when his wife died in 1931, he made over the house in Portman Square, together with the pictures, for the use of the new institute until such time as permanent accommodation could be found for them.
In the event the Portman Square house was to be the institute’s home for almost sixty years.
Rihanna has been pictured cosying up to a mystery man while on holiday in Spain this week, whipping many of her fans into an investigative frenzy.
