Teacher and broadcaster in Fredericton In 1919 Mary Grannan began teaching Grade 1 at the Devon Superior School in the town of Devon, just across the Saint John River from Fredericton. She spent the rest of her 20-year teaching career at the school, where she was noted for her talents as a storyteller and as an author and producer of plays performed by her students. She took private elocution lessons, and participated in amateur theatre productions in Fredericton. In the summer of 1927 she studied at the Vesper George School of Art in Boston, and later contributed editorial cartoons to the Daily Gleaner, a Fredericton newspaper. In April 1936, while still teaching full-time, Mary Grannan began broadcasting on CFNB, a private radio station in Fredericton. One of her programs, a comedy series entitled Aggravating Agatha, became a popular success in the local market.

On the other hand, they expressed an interest in increasing children's radio programming, and Mary Grannan developed the idea for her Just Mary program to meet that requirement. The program, in which she read her original children's stories, appeared first on CFNB in November 1937. It was carried on the eastern radio network of the CBC during the summer and the Christmas holiday season of 1938.
