Rose M. Tettenhorst (nee Huehnerhoff) was married to Dale J. Tettenhorst (1935-1978). She worked as an administrative assistant at Edison Brothers Stores, Inc. in St. Louis. Her boss was president of the company, BernardAlan Edison.

Rose was active with the International Association of Administrative Professionals (IAAP) on the local, national and international levels. Following her death, the local chapter named an annual award in her honor.

Her boss was a coin collector who desired some anonymity for his coin transactions. Invoices were addressed to Rose M. Tettenhorst or R. M. Tettenhorst. Eventually he adopted the pseudonym R. Tettenhorst for hiscollecting interests.

When Rose died in 1989, word of her death came to the attention of some collectors who were familiar with the R. Tettenhorst name. There was some brief confusion from those who thought it was the half cent collector whohad died.
