1998. The southern block of Dwinelle Hall contains three levels of classrooms as well as four lecture halls, and the northern block houses seven stories of faculty and department offices. It is named after the lawyer and politician John W. Dwinelle, who introduced the Organic Act establishing the University of California. Its rooms are strangely numbered both because Dwinelle Hall was built with entrances on different levels on a slope and because its expansions were numbered differently from the original building. Because this confusing building is host to both large lecture classes and numerous discussion classes, it is sometimes called the "freshman maze." 1956 Long Range Development Plan In 1955, to transform the A & E study into a Long Range Development Plan, the Regents appointed a Committee on Campus Planning that included Regent Donald H. McLaughlin as chairman, Chancellor Clark Kerr, and William Wurster, who was both Campus Consulting Architect and dean of the College of Architecture. The plan was published in 1956. Wurster championed the development of high-rise buildings to ensure that open spaces could be preserved, codifying the 25% coverage ratio, which also would "restore the campus to its old sculptural form." He also retained Brown's shortened main axis and first proposed the development of what would become Memorial Glade, north of Doe Library; in the immediate aftermath of the war, that space was occupied by temporary buildings. Student circulation was considered, with a ten-minute class change time proposed. Thomas D. Church succeeded Halprin as consulting landscape architect for the campus in 1957, and oversaw the removal of most vehicle traffic through campus. Initial development under the new plan included Morrison and Hertz Halls, the Anthropology and Art Practice Building, the first phase of the Student Center, Campbell Hall, O'Brien Hall, and McCone Hall. University Hall on Oxford Street and first two units of the Residence Halls in Southside were also built during this time. For the first time, large-scale demolition claimed buildings dating back to the 1880s. Hertz and Morrison Halls Hertz and Morrison Halls, both designed by Gardner A. Dailey & Associates, were completed in 1958. They are located south of the Faculty Club near the southeastern edge of campus and connected to each other by a covered walkway. Both buildings have gable roofs, and compared to other post-War developments, both are relatively small in size: Hertz Hall is a 4-story concert hall, and Morrison
