Time and Life Building, undated postcard.

Opened in the spring of 1937, 9 Rockefeller Plaza (now called 1 Rockefeller Plaza) is a 36-story skyscraper. Completed in 114 work days, a month ahead of schedule, it was the eleventh building in the Rockefeller Center complex. The Art Deco office building was designed by Rockefeller Center's associated architects, led by L. Andrew Reinhard and Wallace Harrison. Early tenants of the building included the Girl Scouts, a number of advertising agencies and publishing houses, and the Museum of Modern Art (who stayed until their new building was completed 1939). The largest tenant, who moved in a year after the building opened, was Time, Inc, the publisher of Time Magazine, Life, and Architectural Forum, among others. This tenant gave the building its name; it was the original Time-Life Building (today the 1957-completed building at 1271 Sixth Avenue is the Time-Life Building).
