Isabella de la Houssaye, a lawyer, businesswoman, and prolific endurance athlete lost her battle with Stage 4 non-small-cell lung cancer, but is being remembered for her lasting legacy, writes Richard Sandomir for The New York Times. 

De la Houssaye was often seen mountaineering, and participating in marathons and triathlons with her children, a journey she first began on her own during the 1990s. 

She and her husband, David W. Crane, encouraged their children to participate in endurance activities at a young age to help teach them valuable skills, such as patience, focus, and perseverance.

Her athletic activities were temporarily stopped in January 2018 when she was diagnosed with lung cancer.

Her cancer spread, but two drugs targeted for non-small-cell lung cancer and allowed her the strength to finish two marathons later that same year.

Beyond running marathons and climbing mountains, de la Houssaye was also a businesswoman. 

In 2008, she became co-owner of Material Culture, an art and antiques retail store and auction house in North Philadelphia. 

De la Houssaye continued her athletic activities until nearly the end. 

She ultimately succumbed to her illness at age 59, and is survived by her husband, five children, her mother, sisters, and brother.
