Mary Susan (Schilde) Williamson was born March 9, 1947 in Cushing, Oklahoma, the daughter of Carl Edwin and Mavorine (Weldon) Schilde. She completed this life at her Oklahoma City home on Friday, January 31, 2025 at the age of 77.

Susan was raised in Oklahoma City where she graduated from John Marshall High School. She went on to attend the University of Oklahoma graduating from the School of Pharmacy. Susan married Richard Kent Williamson on September 22, 1968. They made their home in Oklahoma City where they raised two sons.

Susan had a distinguished career as a hospital pharmacist. Afterwards, she joined an oncologist who was treating cancer patients and doing research in his office. There she established the first licensed pharmacy in the state of Oklahoma that was allowed to mix chemo within a doctor's office and be administered by the nurses there rather than at a hospital. She later joined a startup company where she established a pharmacy to mix IV fluids for home infusion. These IVs were delivered to the patient's home and administered by the nurses.

Susan began playing competitive duplicate bridge and found her retirement life, going on to earn the prestigious rank of Life Master. She established the Fun and Games Duplicate Bridge Club in North Park Mall in 2016, which became one of the largest and nicest bridge clubs in the USA. To grow the club, she taught beginning bridge lessons to many new players. With the club temporarily closed during the COVID-19 pandemic, she kept the club together by teaching bridge and holding games online. She soon found that not just club members but people around the USA were attending her free Zoom bridge lessons. Eventually people from several countries around the world started logging in to her Saturday morning sessions or viewing her YouTube classes. Susan was a brilliant personality. She will be missed by bridge players around the world.

Susan is survived by her husband of 56 years, Richard Williamson, retired CPA; her sons, Stuart Williamson, Software Engineer, and his wife Kristin Williamson, Children's Librarian; Clinton Williamson, MD, and his wife Natalie Williamson, MD; and her grandchildren, Heidi Williamson, Elizabeth Williamson, Timothy Williamson, Maddy McAllister, Max McAllister, and Mason McAllister. Susan was preceded in death by her parents.

A memorial service will be held in May at the Bridge Club in North Park Mall.

In lieu of flowers, memorials may be made to Fun and Games Duplicate Bridge, Attn: Jane Hughes, 11928 N. May Ave., Oklahoma City, OK 73120.
