The Alliance of the Indianapolis Museum of Art was founded in 1958 and planned lectures, black tie balls, and related activities in order to raise funds for the museum.[5] Major gifts included a $350,000 contribution in 1979 toward the $40 million centennial endowment campaign[135] and a $500,000 contribution toward the IMA's 1990 expansion. By 2007 the Alliance had provided purchase funds for over 300 works of art.[5] The Contemporary Art Society was formed in 1962 to acquire contemporary art for the museum's permanent collection.[3] In 1963, the first major acquisition consisted of 65 works.[4] The Horticultural Society was founded in 1972 to contribute to the care and education of the museum's gardens and grounds, raising $65,000 in 1989 toward the restoration of Oldfields' gardens.
