Charles Greene Baumgartner was born in 1881. He was a member of the Thencanic Society and graduated from the Model School in 1900. He died in Connecticut in 1968.

A literary and debate club at the Model School from 1882 to 1917. The members (only young men) focused on improving their oratory skills, personal appearance, and general comportment, with one member serving as "Critic" to evaluate the boys' behavior during each meeting. The literary aspects of the Society led to the publication of "The Signal" in 1885--while it started as a literary magazine through the Thencanic, it quickly escaped the Society's control and became a general Normal/Model School periodical. This club ended when the Model School closed in 1917. This version of the Thencanic should not be confused with the later revival in the 1930s with college students.
