The woman who made Martha Stewart the domestic powerhouse that she is today has died. Martha's mom, Martha Kostyra (a.k.a. "Big Martha") passed away in a Connecticut hospital after suffering a minor stroke. She was 93. In 2003, The marthas appeared on Larry King Live together. "And you know, the first thing people say to me when they meet me for the first time" the elder Martha asked Larry, "They'll say, - Did you teach her everything she knows? - Well, I'll take the credit, certainly." Martha Stewart announced the sad news of her mom's death on her blog over the weekend, saying her mentor led "an amazing life" and was her "favorite guest." She also posted video clips of them cooking together, as a tribute. Our condolences.
