Arthur Frederick Ostrander
Arthur Frederick Ostrander, Sr. (February 14, 1895 – February 1978), was an assistant scientist. He worked with inventor George Poe. In his childhood he worked with Poe (mid-1907 to 1908), who taught him how an artificial respiration device functions. His assistance to Poe was instrumental in the successful development of the respiration device, as he performed the fine detail work and metal fabrication that Poe could no longer do.
