The Alexander-Rideout Collection consists of material relating to Sir George Alexander and St. James's Theatre assembled by Alexander's distant relative, Nigel Rideout. The British actor-manager Sir George Alexander (1858-1918) was born Alexander George Samson in Reading, England. He began acting in amateur theatricals in 1875, and four years later embarked on a professional acting career, making his London debut in 1881. He played many roles in the leading companies, including Sir Henry Irving's Lyceum. In 1890 he produced his first play at the Avenue Theatre and in 1891 he became the manager of St. James's Theatre. Here he produced several of the major plays of the day such as Lady Windermere's Fan by Oscar Wilde (1892), The Second Mrs. Tanqueray by Sir Arthur Wing Pinero (1893), The Importance of Being Ernest by Oscar Wilde (1895), and The Prisoner of Zenda by Anthony Hope (1896).

The Pearl Mary Teresa Richards Craigie Papers are comprised of two boxes consisting of letters written to Mrs. Craigie by various members of London society, and of the London theatrical and literary worlds concerning her novels and plays. The largest groups are those from James E. C. Welldon, headmaster of Harrow and Bishop of Calcutta, and those from Sir George Alexander, who produced her plays. There are also letters addressed to Mrs. Craigie's father, John Morgan Richards, concerning the "Life" of Mrs. Craigie which he edited after her untimely death at age 38.
