Martha Stewart is mourning the loss of her youngest sister, Laura Kostyra Plimpton, who died suddenly of a brain aneurysm at age 59 on Tuesday, Aug. 5. In a blog post on her website hours after Plimpton's death, Stewart memorialized her beloved sibling's "extraordinary" life as a wife, mother, sister, and employee. 

"Laura worked for me and the company for more than 25 years," the lifestyle guru wrote. "For the past several years Laura edited, researched, and often wrote, captioned, and photographed content for this blog and The Daily Wag." 

Stewart went on to recall Plimpton's March 4 birth as the youngest of the six Kostyra siblings. "Our mother wanted to name her Dorothy, but we persuaded her to name her Laura instead," she shared. "We still don't know why we didn't like the name Dorothy, but Laura was beloved by all as Laura."

This week started like any other. According to Stewart's blog, Plimpton awoke on Monday morning at 5:30 a.m., "did her one hour of elliptical and treadmill, then showered and felt ill enough to call her husband Randy for help." She was then taken to Norwalk Hospital in Connecticut, where doctors determined that "she had suffered a massive brain aneurysm."

"Laura left a living will so she was kept on life support until today so her three children could say their goodbyes, and the testing could be completed for organ donation," Stewart wrote. "We are so sad but also happy that Laura had the foresight to donate so many healthy organs to needy people."

Plimpton is survived by her husband, Randy; her three children, Christopher Herbert, Sophie Herbert Slater, and Charlie Plimpton; and her two children-in-law, Tim Long and Dan Slater. Stewart ended her blog with a plea for readers to keep the family in their thoughts, writing, "Laura deserves the very best; she was an extraordinary employee, mother, wife, and sister."
