by Joseph C. (Joseph Charles) Sindelar
Active in the early 1900s, Joseph Charles Sindelar wrote books for children as well as practical books for teachers. Library and public-domain catalog records identify him as born in 1885, and surviving editions show a body of work aimed at schools, reading aloud, and seasonal programs.
His books include Morning Exercises for All the Year: A Day Book for Teachers and collections such as Closing Day Entertainments and Washington Day Entertainments. The titles linked to him suggest a writer interested in helping teachers fill the school year with recitations, dialogues, songs, and short pieces that could be used in class or on stage.
Catalog listings also connect him with children's stories, including animal-themed works such as Father Thrift and His Animal Friends and Nixie Bunny in Holiday-Land. Even from the titles alone, his work feels cheerful, practical, and closely tied to the everyday world of classrooms and young readers.
