Martha Stewart is looking back on the life of her youngest sister Laura Kostyra Plimpton following her death on Wednesday.

"Laura worked for me and the company for more than 25 years. For the past several years Laura edited, researched and often wrote, captioned and photographed content for this blog and The Daily Wag," the TV personality writes on her blog about her sibling, the youngest of six. "She was born on March 4, 1955. Our mother wanted to name her Dorothy, but we persuaded her to name her Laura instead. We still don’t know why we didn’t like the name Dorothy, But Laura was beloved by all as Laura."

Stewart, 73, goes into detail as to the cause of her sister's death, writing: "She woke up Monday morning at 5:00 A.M. to do her daily one hour of elliptical and weight training. She made coffee for her husband Randy and they completed the New York Times crossword puzzle together. Then she took a shower and suddenly felt ill and called for Randy's help. She was rushed to the hospital where they said 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. We are so sad but also happy that Laura had the foresight to donate so many healthy organs to needy people."

In addition to the short post about Plimpton, Stewart also included a gallery of photos of her sister. "Please keep her husband Randy and her three children, Christopher Herbert, Sophie Herbert Slater and Charlie Plimpton, and two sons-in-law Tim Long and Dan Slater, in your thoughts," she writes. "Laura deserves the very best; she was an extraordinary mother, wife, and sister."
