Louise Wilson, OBE, head of the MA Fashion at Central Saint Martins, died in her sleep last night. At CSM I was so lucky to have spent any time with her at all, since I was on the journalism course. But I had the opportunity to sit in countless crits with Louise and even though my direct interactions with her were more limited than those of womenswear and menswear students, she has always been the greatest and most important looming figure and influence in my career. She taught every one of us what it means to be ruthless, uncompromising, visionary, relentless. Louise was brutal, but she was always right. She's gone now, and the world will be poorer for it.
