On June 18, 1923, our Omicron Chapter was installed at University of Michigan in Ann Arbor, Michigan. With its installation Omicron Chapter became the furthest west chapter in the Fraternity at the time of its chartering. The newest of 53 campus fraternities, Alpha Phi Delta had a successful first five years, but a struggle last five years. By 1931, Alpha Phi Delta diminished enough to be removed from the campus interfraternity council. On November 26, 1932 the Executive Committee of Alpha Phi Delta placed Omicron on suspension. In spite of a number of visits by the Grand Consul in 1933 to revive Omicron's fortunes, the situation was too far gone. It seems that the morale of the few Omicron brothers left on the campus was poor and the Chapter's alumni in the Detroit area failed to support and encourage them in their hour of need. As a result, the charter was recalled from Omicron in late 1933. Thus, Omicron Chapter attained the singular infamy of being the first Chapter of Alpha Phi Delta to close. By the start of the new year in 1934, the chapter officially ceased to be, after initiating 55 men over 10 years (most between 1925-1928). Nearly 50 years later, a re-activation effort saw Omicron brought back to the University of Michigan campus. Between 1980-1984, the revived Omicron took in 33 members, but only three more members in 1985. Omicron official was shuttered in 1987, after an eight year reactivation.

Once Omicron was established, the Chapter attained a campus house at 807 South State Street, Ann Arbor, Michigan (pictured above). However on September 23, 1928 tragedy struck Omicron as its house caught fire and was gutted by the ravages of flames and sooted by smoke damage. The fire was of enough consequence to merit coverage in the St. Joseph Herald-Press, one of the area newspapers. The Chapter got to work on restoring its home, and did so. However, that fire also marked the period that began the decline of Omicron Chapter -- perhaps owing to a lost semester of activity on a competitive campus. What is known is that the chapter, without insurance protection, ultimately lost its house property because of the debts it was forced to assume to restore its home. That debt when coupled with a smaller membership made the maintaining of its house untenable. In 1931, with a greatly diminished roster, the Chapter moved to smaller quarters at 201 N. High Street in Ann Arbor, and soon after closed. The South State Street was torn down a few years later, and a newer house stands on that site; neither the house nor the street where the High Street house existed remain -- due to urban development High Street was truncated, and the area where that house is now a business park.
