Joanne was born on May 2, 1938 in Gary, Indiana to Clark C. Rittenhouse and Mary Margaret Rittenhouse (Oberle). She graduated high school from St. Francis High School, Lafayette, Indiana in 1956. She received a B.S. degree in pharmacy from Purdue University in 1960. She would later receive a B.S. degree in psychology from the University of Iowa in 1986. Joanne had a 50-year career in pharmacy working in retail drug stores and hospital pharmacies from 1960 until her retirement in 2010.
Joanne married Dr. Ronald D. Schoenwald, pharmacy professor, on August 23, 1963 in Phoenix, Arizona. They had two children: David in 1964, and Debra in 1965, both born in San Jose, California.
Their careers took them crisscrossing the country living in Arizona, California, Indiana, Washington, Texas and Iowa, with finally retiring back in Arizona. Joanne enjoyed raising exotic endangered birds, studying health, fitness and nutrition, reading books on philosophy and the classics, attending Spanish classes, hiking, and fictional writing.
