Following the death of Sir Hugh Lane in the sinking of the RMS Lusitania in 1915, an oversight in his will meant that the collection of European modern art he had intended to go to Dublin controversially went to the Tate instead, which expanded its collection to include foreign art and continued to acquire contemporary art. In 1926 and 1937, the art dealer and patron Joseph Duveen paid for two major expansions of the gallery building. His father had earlier paid for an extension to house the major part of the Turner Bequest, which in 1987 was transferred to a wing paid for by Sir Charles Clore.
