Katharine S. Brown, Glenna Tinnin and Jane Ogle of Tinnin, Brown, Inc. were actors' managers whose clients included E. H. Sothern and his wife, Julia Marlowe.
Marlowe and Sothern first appeared together as Romeo and Juliet in 1904 and reigned for a decade or more as America's foremost Shakespearian players. In the late 1920s Sothern gave dramatic readings around the country and Marlowe was retired from the stage.
