Founded at various times in the university's history, the professional schools originally were scattered throughout Chicago. In connection with a 1917 master plan for a central Chicago campus and President Walter Dill Scott's capital campaign, 8.5 acres (3.44 ha) of land were purchased at the corner of Chicago Avenue and Lake Shore Drive for $1.5 million in 1920. The architect James Gamble Rogers was commissioned to create a master plan for the principal buildings on the new campus which he designed in collegiate gothic style. In 1923, Mrs. Montgomery Ward donated $8 million to the campaign to finance the construction of the Montgomery Ward Memorial Building which would house the medical and dental schools and to create endowments for faculty chairs, research grants, scholarships, and building maintenance. The building would become the first university skyscraper in the United States. In addition to the Ward Building, Rogers designed Wieboldt Hall to house facilities for the School of Commerce and Levy Mayer Hall to house the School of Law. The new campus comprising these three new buildings was dedicated during a two-day ceremony in June 1927. The Chicago campus continued to expand with the addition of Thorne Hall in 1931 and Abbott Hall in 1939. In October 2013, Northwestern began the demolition of the architecturally significant Prentice Women's Hospital. Eric G. Neilson, dean of the medical school, penned an op-ed that equated retaining the building with loss of life.

Multiracial people who wanted to acknowledge their full heritage won a victory of sorts in 1997, when the Office of Management and Budget (OMB) changed the federal regulation of racial categories to permit multiple responses. This resulted in a change to the 2000 United States Census, which allowed participants to select more than one of the six available categories, which were, in brief: "White," "Black or African American," "Asian," "American Indian or Alaskan Native," "Native Hawaiian or other Pacific Islander," and "Other." Further details are given in the article: Race (U.S. census). The OMB made its directive mandatory for all government forms by 2003.

When did the OMB change racial guidelines for the census form?
Answer:
1997
