Joseph C. (Joseph Charles) Sindelar

Born in 1885, Joseph C. Sindelar — short for Joseph Charles Sindelar — is identified in library and public-domain catalog records as an American writer and editor whose books include children’s stories as well as collections made for teachers and school programs.

His surviving bibliography shows two clear sides to his work. One is playful children’s fiction, including books such as Father Thrift and His Animal Friends and the Nixie Bunny titles. The other is educational and ceremonial material for classrooms, with books like Morning Exercises for All the Year, Closing Day Entertainments, and Lincoln Day Entertainments.

Much of his work was published in the early 1900s and has remained accessible through library catalogs, Project Gutenberg, and audiobook volunteer archives. I couldn’t confirm many personal biographical details beyond his name form and birth year, so this overview focuses on the writing career that can be clearly documented.
