Hon. Thomas Emmett Brennan Sr.

May 27, 1929September 29, 2018

The Honorable Thomas E. Brennan, Sr. died peacefully on September 29, 2018 in Lansing, Michigan surrounded by family. He was 89. Brennan was the founder of Thomas M. Cooley Law School in Lansing. He was also the 81st Justice of the Michigan Supreme Court and the youngest Supreme Court Chief Justice in the history of the State of Michigan. More than any of these significant career accomplishments, Brennan treasured his role as sponsor and mentor to generations of lawyers who attended Cooley Law School, his loving family, and his lifelong friends. To know Brennan was to know his intellect, creativity, charm, quick wit and irrepressible sense of humor always tinged with an Irish glint. Born on May 27, 1929 in Detroit, Michigan, Brennan graduated from Detroit Catholic Central High School, where he excelled in forensics. He attended the University of Detroit and earned a law degree from the University of Detroit Law School in 1952. In 1951, he married the love of his life, Pauline Mary (Polly) Weinberger, with whom he had six children. Immensely proud of his large Irish Catholic clan, Brennan often involved family in his various professional pursuits, from political campaigns to the inception of the Thomas M. Cooley Law School. He was quick to credit Polly’s invaluable support for virtually all of his success. Even so, success did not come easily in the early years of Brennan’s political career. He failed two attempts as a candidate for the Michigan House of Representatives in 1952 and 1954, and lost to John Dingell, Jr. for the U.S. Representative from Michigan’s 15th congressional district in December, 1955.

In 1953, he joined the law firm of Waldron, Brennan, Brennan, and Maher, with whom he worked until 1961, when he was elected to a seat on the Common Pleas Bench. In 1963, he was appointed by Michigan Governor George W. Romney to the Wayne County Circuit Bench, and in 1964 he was elected to that same position. In 1966, at the urging of Governor Romney, Brennan sought the nomination of the Republican Party as Associate Justice of the Michigan Supreme Court. He won the nomination, and the election. In 1969 and 1970, Brennan served as Chief Justice, the youngest Justice to serve in that capacity. While serving on the Bench, Brennan received numerous requests for law school recommendations which inspired his vision for a new, non-profit law school in Lansing, Michigan. Noting that many qualified students were refused law school admission, he was determined to eradicate academic elitism and make legal education accessible to all capable students. Brennan incorporated Thomas M. Cooley Law School in 1972 with the belief that “An educated citizenry that understands the law is critical to the strength and progress of the nation.” Brennan left the Supreme Court on December 6, 1973, to dedicate his professional career to the fledgling law school and ensure its success. Brennan served as first Dean of Cooley Law School until 1978, when he became its first president. Under his magnetic leadership, Cooley Law School grew from its initial class of 76 students to become the largest accredited law school in the nation. Known for ingenuity and perseverance, Brennan designed and instituted numerous unprecedented innovations, including the law school’s year-round schedule that allowed multiple first term classes to start each year. He is credited with founding the Cooley Legal Authors Society, the Student Bar Association, the Scholastic Review Board and the Thomas M. Cooley Law Review. He also composed the law school’s alma mater.

During his tenure at Cooley Law School, Brennan ran unsuccessfully for U.S. Senator from Michigan in 1976, and for Lieutenant Governor of Michigan in 1982. Brennan retired from Cooley Law School in 2002. The Thomas E. Brennan Law Library in Lansing is named in his honor. Combining insight and levity, Brennan was a captivating orator and engaging storyteller. He authored a self-published novel entitled The Bench in 2000, a memoir called Starting a Law School in 2007, a book entitled The Article V Amendatory Constitutional Convention: Keeping the Republic in the Twenty-First Century in 2014, and a blog, oldjudgesays, which ran from 2008 to 2017. New ideas energized Brennan, whether he was striving to establish a United States Constitutional Convention or trying to develop an American Golf League. An avid golfer, Brennan made a hole-in-one on five lucky occasions.

He will be deeply missed by his beloved Polly and their children: Thomas, Jr. (Julie), Margaret (David) Radelet, John (Catherine), William (Lisa), Marybeth (James) Hicks, and Ellen (Peter) Campbell; nineteen grandchildren; nine great-grandchildren; siblings Raymond (Loretta) of East Lansing, Michigan, Mary (James) Bernard of Fraser, Colorado, and Sally Giraud of Westland, Michigan, and sister-in-law Patricia Brennan of Rochester Hills, Michigan. He is preceded in death by parents Joseph and Jeannette Brennan and brother, Joseph Terrence, Jr.

A Funeral Mass will be held Thursday, October 4, 2018, 10 a.m., St. Thomas Aquinas Catholic Church, 955 Alton Road, East Lansing, MI with concelebrants Rev. Michael Murray, Rev. Msgr. Michael D. Murphy, Rev. Richard Elmer, C.S.B., Rev. Charles Irvin, Rev. Joseph J. Krupp and Rev. Gary Koenigsknecht officiating.

I first became acquainted with Judge Brennan in connection with his efforts to promote an Article V constitutional convention. Later on, I became a frequent gentle opposing commentator from the left on his Old Judge blog. He always treated me with grace and respect despite our political differences. I greatly admired his writing ability.

I am a proud graduate of Thomas M. Cooley Law School. President Brennan was a very humble and generous man. When I experienced some issues with my tuition payments President Brennan himself met with me and asked me how could he help me. We both came up with a solution that fit my budget. I thank God for his help and compassion. He truly cared about people. I never forgot his kindness.

My sincerest condolences to the Brennan Family. May God continue to comfort you and your entire family remain in my prayers. Rest In Peace President Brennan, your light is surely shining bright in Heaven!

Tom Brennan hired me late in 1974. I started to teach at Cooley in January,1975 I am still here half a lifetime later. Over the years he was kind to me on many occasions. He did a lot for me and I deeply appreciate it. He was a wonderful man. Jack Rooney
