From 1907 through 1916, he and his wife conducted an intensive survey at the Public Record Office in London. The Wallaces discovered the court record papers of the dispute between Alleyn and the owners of The Theatre, an account of which he published as The First London Theatre: Materials for a History. They also discovered Shakespeare's 1612 deposition in the Bellott v. Mountjoy lawsuit, and records of the suits Keysar v. Burbage (1610), Ostler v. Heminges (1615), and Witter v. Heminges and Condell (1619), among a range of other documents, yielding important new knowledge in the study of Jacobean drama. The Wallaces' work provided a vastly improved comprehension of the role of the children's companies in English Renaissance drama.
