Blanche L. Rieth, 90, passed away Tuesday, January 28, 2025, in Serenity Place, St. Martin's Village in Rapid City, SD. Blanche was born February 17, 1934, in Seattle, WA, to Marjorie Reardon and Fred E. Altman. She was raised by great grandparents, grandparents, and her mother Marjorie and stepfather Willard S.

Blanche lived in and attended schools in many cities due to her stepfather being in the Navy; including, Seattle, Glenwood Springs, CO, Boston, MA, and Santa Barbara, CA.  She received nurses training in Santa Barbara, where she met the love of her life, Dr. Robert David Rieth. They were united in marriage on December 28, 1954. They raised eight children together for several years in San Francisco, CA, fourteen years in Thermopolis, WY, and finally, in their home from 1978 in Rapid City, SD.

Blanche's entire life was devoted to her husband and eight children, and later, twenty-two grandchildren and six great grandchildren. She was a compassionate, giving person who always wanted to help others in need. Her hobbies included gardening, bird-watching and feeding her birds, music, playing tennis, swimming, ice-fishing, dancing, sewing, artwork, jewelry, cooking, playing games on her iPad, traveling to Deadwood to play the slots, and in later years, playing Bingo. She was thrilled to win little candy bars!
