Sachie was the most reticent of the Sitwells, eschewing the publicity surrounding his siblings to concentrate on writing, and family life at Weston.
At Weston, he produced virtually all his works of note. These included “Southern Baroque Art”, his famous 1924 study of Spanish and Italian painting, architecture and music, and books on Mozart and Liszt.
Like his siblings, he wrote poetry but refused to publish it for many years. In 1967, a selection of his poems was published in Poetry Review, including an elegy for his beloved sister Edith.
Sachie married a Canadian beauty, Georgia Doble, in 1925 and had two sons, Reresby and Francis. Reresby inherited the Baronetcy of Renishaw when his uncle Osbert died in 1969. In the 1940s, Sachie served as High Sheriff of Northamptonshire.
He kept regular writing hours, maintaining the same daily schedule on weekends and holidays, even on Christmas day. His output was prolific – more than 80 works until the death of his wife in 1980.
Sachie died in 1988, aged nearly 91. His portrait by Graham Sutherland hangs over the mantelpiece in the hall at Weston.
