After two years as Permanent Secretary, Lindsay was named as the Ambassador to the United States in November 1929,[11] and took up the position early the next year.[12][13][14] He was the first ambassador to move into the brand-new British embassy in 1930,[15] and remained in Washington for almost a decade, retiring in June 1939 to be replaced by Lord Lothian.[6]
Lindsay served an extraordinarily long term of nine years as U.S. ambassador, also as the Dean of the Diplomatic Corps from July 1934 to August 1939,[16] his tenure being extended because of his effectiveness as a diplomat and the growing importance of American assistance during the years leading up to World War II.[17]
His last major official act as ambassador was to host the 1939 Royal Garden Party for King George VI and Queen Elizabeth during the first-ever visit to the United States by a reigning British monarch.[18][19] The Royal Garden Party at the British embassy was considered the social event of the year in Washington.[20][21][22]
Lindsay was married twice, both times to Americans; in 1909 to Martha Cameron, daughter of J. Donald Cameron (a U.S. Senator from Pennsylvania and the 32nd Secretary of War) and his wife Elizabeth Sherman Cameron;[27] and after his first wife's death in April 1918, he married prominent landscape gardener Elizabeth Sherman Hoyt, daughter of Colgate Hoyt, in 1924.[28] Both wives were grandnieces of William Tecumseh Sherman. There were no children from either marriage.[1][6]
Lindsay died in Bournemouth in August 1945, aged 68.[2] Lady Lindsay died in September 1954, aged 68.[29]
