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 letters, most of which are undated, were written between September 10, 1869 and December 15, 1894. These limits are not exact; it is unlikely that any letter in this group was written before the first date, but some of the notes may come from the months after December 1894. The works chiefly concerned are Dumas' La femme de Claude and La route de Thebes, the first of which was dedicated to Favre. The letters show how important Dr. Favre's friendship and counsel were to Dumas, and in the correspondence one can trace the evolution of the dramatist's technique of the theater.

The collection contains letters to Mr. Miles from artists, composers, singers, authors, journalists, publishers and politicians discussing their current works and future projects in their respective fields. Of special interest are James Ashcroft Noble's letters (53) to Mr. Miles. Mr. Noble, critic and author, describes the corrections that he is making in his articles to be included in The Poets and the Poetry of the Century, vol. VIII, 1892, edited by Mr. Miles. Two poems "Love's Irony" and "The Old Amati" by Frederic Edward Weatherly are included in the collection.
