Baird, hired by Weird Tales publisher J. C. Henneberger, put out the magazine's premiere issue, dated March 1923. Over the course of the next year, Baird published some of the magazine's most famous writers, including H.P. Lovecraft, Clark Ashton Smith, and Seabury Quinn.
Baird—in marked contrast to his successor—accepted everything that Lovecraft submitted to the magazine, including "The Hound", "Arthur Jermyn", "The Statement of Randolph Carter", "The Cats of Ulthar", "Dagon", "The Picture in the House", "The Rats in the Walls", "Hypnos" and "Imprisoned with the Pharaohs". He did, however, insist that Lovecraft retype his first submissions using double spacing, causing the author to remark, "I am not certain whether or not I should bother."
Under Baird's editorship, Weird Tales lost a considerable amount of money—estimated at $51,000. After the April 1924 issue, Henneberger fired him and offered his job to Lovecraft. When Lovecraft declined, the publisher made Farnsworth Wright, until then Baird's assistant, the editor of Weird Tales, a position he held until 1940.
Baird remained as editor of another of Henneberger's titles, Detective Tales. In this post, he rejected Lovecraft's "The Shunned House" in July 1925. Detective Tales was sold off, and Baird remained editor when it retitled as Real Detective Tales.
