Farrell Frentress spent 40 years raising funds for top Chicago cultural institutions. “He once aspired no higher than to run a YMCA. But he worked with leaders in Chicago opera as he helped to sustain Lyric’s rebound from near-insolvency. He helped reshape the board and culture at the parent of WTTW-Ch. 11 and WFMT-FM 98.7 and finance an ambitious expansion there.”
