László completed his education in Vienna, Austria before moving to Stuttgart, Germany, where he rapidly established himself as a prominent designer, winning the admiration of, among others, Salvador Dalí.

László rented the entire building from the owner when it was still incomplete and he immediately took on the task of designing the interiors, the exterior details and all of the furniture complete with fabrics.

He designed department stores for Bullock's Wilshire, Goldwaters, Robinson's,[3] Saks Fifth Avenue, Halls (Crown Center, Kansas City), Hudson's Bay and Ohrbach's.

[9] As evidence of László's long and highly regarded career, photographs, renderings and descriptions of his work appear in books and periodicals from every decade starting in the 1920s and are still being published in the 21st century.

[11] Autobiographical information is available on László's life in the publication "Designing With Spirit," an oral history conducted by the University of California, Los Angeles.

His work is occasionally displayed at the Museum of Modern Art in New York City and is frequently seen in national and international retrospectives on 20th-century design.
