BERKELEY, CA.- Prominent urban landscapes architect Karl Linn, 81, died. He was the landscape architect for Ludwig Mies van der Rohe's Seagram Building in New York. He also designed the interior landscaping for the Four Seasons Restaurant. In the late 1950's he began to focus on making community gardens in depressed neighborhoods.

Monika Bauerlein, a San Francisco resident who's writing a book about community gardens, said, "While community gardens are often insulated from the world around them-there are many with fences or signs discouraging casual visitors-Karl's are designed as public spaces from the start. Private-property owners are privileged to have secure backyards. Community gardeners who rely for sustenance on the food they grow should have the same security.

Karl Linn was born in Dessow, Germany on March 11, 1923. In 1934 the Linn family fled to Palestine. Karl Linn graduated from the Kadoorie Agricultural School in Palestine. He later helped found a kibbutz, Maagan Michael.

In 1946, Mr. Linn went to Switzerland to study psychoanalysis. Later he settled in New York and helped found a school for emotionally disturbed children.
