I just heard on the radio that Swedish designer Nils Erik "Nisse" Strinning has died at the age of 88. He was, among other things, the man behind the best-selling String bookshelf.
"Certain things are so closely associated with a particular time that they become timeless. There is no better example of this than the String shelf system designed by Nisse Strinning in 1949." (from the String site)
