LouAnn was born January 27, 1931 in Morris, Illinois to parents Isabelle (Bretthauer) Walker and Randall Ervin Walker. The family later moved to Yorkville, IL where she graduated from Yorkville High School in 1949. She completed a two-year pre-nursing program at Blackburn College in Carlinville, IL and graduated from Nursing at Wesley Memorial Hospital in Chicago. In 1954 she received her BA of Nursing from Northwestern University in Evanston, IL. She married Dr. Robert Pierre while living in Chicago. They moved to Rochester, MN and raised four children.

Lou was proud of and loved being a nurse and had a long career with The Mayo Clinic in cardiac research. She volunteered with the St. Mary's Auxiliary and was a docent at Mayowood. She was a very active and inquisitive person and was a voracious reader of all subjects, particularly presidential history and first ladies. She loved gardening, needlepoint and all things Christmas.
