Born to Scott and Addie Leidigh, Bach graduated from St. Luke's School of Nursing, and received a RN degree in 1924. She joined the Order of Eastern Star in 1918, and was active there for 92 years. Also, in 1937, she joined Crown Heights Methodist Church. She was Worthy Matron in 1948, and brought into the Oklahoma Centenarian Club in 2001, when she was 102. In addition, she served on the Board of Directors before moving to Texas in 2002, where she lived until her death.
She is survived by two sons and daughters-in-law, as well as assorted relatives.
Bach is, so far, the only supercentenarian listed on GRG's Pending List for 2010 to die without ever seeing validation, as she was added to the GRG's 2010 death index database around 15 July. This is not to say that her age is not proven and true; it simply means that the final documents to prove her age were obtained only after death. Therefore, she never ever appeared on the GRG's list of validated living supercentenarians at any point, and would only have gotten a place on the list after eventual authentication, on all versions of the list between 17 December 2009 and 6 June 2010.
For instance, the GRG and Louis Epstein together reported a record (at that time) 80 supercentenarians on 18 April 2010; the number was later cut to 79 after the discovery of Bernardina Van Dommelen (Belgium)'s death on 16 April 2010. However, after eventual authentication, we now know that there were actually about 90 supercentenarians at that time.
