academically and in extra-curricular activities. The chapter had the highest grade average among all fraternities a number of times during this decade and Brother Charles Parker '27 became the second Zeta Phi to win a Rhodes Scholarship. World War II suspended much of the activity at the university and during the war years the chapter's size was again reduced considerably.

To accommodate the expanding group, the annex at 1307 Willson Avenue was purchased in 1958 at a cost of $50,000. The early 1960s saw continuing progress for the chapter, with high grades and back-to-back intramural titles in 1961, 1962, 1963, 1964, and 1965. The old house at 520 South College and an adjacent structure were torn down in 1963 to make way for a new house. A fund drive among alumni and friends raised nearly $200,000, without which the new facility would not have been possible.

As total Greek membership declined, many fraternities were forced to close their doors in the face of falling memberships and poor funding.

By the mid-1970s, fraternities again began to gain in popularity and the chapter rode the crest of this wave, winning the coveted "triple crown"—grades, intramurals, and singing competitions—roughly every other year.

Between 1974 and 2001 the fraternity won the intramural championship 24 times. The 1980s saw a comeback for the fraternity system that has placed it in the vogue, especially at large midwestern universities such as the University of Missouri.
