The first scholar to doubt Alberti's role as the architect of the Palazzo Rucellai was Julius Schlosser (1929). Schlosser's opinion was seconded by Leo Planiscig (1942), Howard Saalman (1966), and Mario Salmi (1967). Basing his opinion on the tax information which pointed to a later dating for the facade stage of the Rucellai project and the possible precedence of the Piccolomini Palace in Pienza, Mack argued for Bernardo Rossellino' authorship in 1974, receiving support from Forster (1976) and Marvin Trachtenberg (2000). Despite these attempts at rethinking the facade and its date, general support for Alberti remains and strong counter arguments in his favor have been made by Brenda Preyer (1981) and others. While Bernardo Rossellino's role in remodeling the interior of the palace, in constructing the entry passage, and in creating the courtyard is universally accepted, his involvement with the celebrated facade and the date it was executed remain open questions.
