The art world and the design world are mourning the loss of two of their own—one after a long career, the other way too soon.

Louise Bourgeois passed away on Monday at the age of 98. The French-born sculptor was recently working in collaboration with Pritzker Prize winner Peter Zumthor on a Memorial to the victims of the Witch Trials in Varanger, Norway, which is scheduled for completion this summer.

Designer Tobias Wong died on Sunday. The Vancouver native started turning heads in New York City almost a decade ago by transforming works by Karim Rashid and Philippe Starck when he was fresh out of school. He continued to produce witty and provocative work and was named Young Designer of the Year by the Brooklyn Museum of Art in 2006. He was 35.
