William Morse Davidson (December 5, 1922 – March 13, 2009) was a prominent American entrepreneur who served as president, chairman, and CEO of Guardian Industries, a major international producer of architectural and automotive glass. He was also the proprietor of multiple professional sports franchises in North America and earned induction into the Naismith Memorial Basketball Hall of Fame.

As the chairman of Palace Sports and Entertainment, Davidson held principal ownership of the Detroit Pistons (NBA) and the Detroit Shock (WNBA), as well as co-ownership of the Detroit Fury (Arena Football League). Additionally, he owned the Tampa Bay Lightning (NHL) and the Detroit Vipers (International Hockey League). His leadership saw the Pistons capture NBA titles in 1989, 1990, and 2004; the Shock win WNBA championships in 2003, 2006, and 2008; the Vipers secure the 1997 Turner Cup; and the Lightning claim the Stanley Cup in 2004.

Early life and education

Davidson was born in Detroit into a Jewish family on December 5, 1922. He graduated from Central High School in 1940. Pursuing higher education at the University of Michigan, he majored in business at what is now known as the Ross School of Business while participating on the university’s track and field team. During World War II, he served in the United States Navy and played football for the Armed Forces.

Following his military service, Davidson obtained a Juris Doctor degree from Wayne State University Law School in 1949. After practicing law for three years, he transitioned into business, where he successfully revitalized both a wholesale drug company and a surgical supply firm that had been facing bankruptcy.

Early career and family business

In 1957, Davidson assumed control of his family’s Guardian Glass Co., coinciding with its declaration of bankruptcy. Over time, Guardian Glass transformed into Guardian Industries, becoming one of the largest global glass manufacturers with operations spanning Asia, Europe, Africa, South America, and North America. Known for fostering bold leadership and embracing risk-taking, Davidson's tenure was marked by some controversies; between 1965 and 1988, Guardian faced several legal challenges and in 1989 was ordered to pay $38 million to competitor Johns Manville over allegations of technology misappropriation.

Pistons ownership

Although initially aiming to acquire a football franchise, Davidson shifted his attention after an unsuccessful attempt to secure a Tampa expansion team. In late 1974, he purchased the Detroit Pistons from founder Fred Zollner for $6 million. At that point, since their relocation to Detroit in 1957, the Pistons had yet to turn a profit.

Davidson relocated the team first from Cobo Arena—with its 10,000-seat capacity—to Pontiac Silverdome in 1978, followed by a move to The Palace of Auburn Hills in 1988. Notably, The Palace was the first NBA arena funded entirely through private capital. To help finance its $90 million construction cost, The Palace introduced lower-level suites—a pioneering revenue model at the time.

Under Davidson’s ownership, the Pistons became league leaders in amenities including a dedicated cutting-edge practice facility. He was also a trailblazer as the first NBA owner to acquire a team airplane—the "Roundball One"—which was later upgraded to "Roundball Two," featuring plush seating and advanced video technology. Davidson actively promoted global marketing initiatives for the NBA and held the position of chairman of its Board of Governors.

By 2009, the franchise value of the Pistons had surpassed $430 million. Davidson publicly affirmed his intention to keep ownership within his family following his passing.

In 1999, after an unsuccessful bid for the Tampa Bay Lightning franchise, Davidson eventually purchased it for $100 million—a figure later appraised at approximately $136 million. Under his stewardship, Tampa Bay won their first Stanley Cup in 2004. He sold this team in 2007.

Davidson received recognition with his name displayed on The Palace floor alongside Pistons legends and was inducted into both the Naismith Memorial Basketball Hall of Fame in 2008 and the Jewish Sports Hall of Fame.

At the time of his death, Davidson lived in Bloomfield Hills, Michigan with his wife Karen. He was survived by two children and three stepdaughters. His business endeavors resulted in an estimated net worth of $3.5 billion, placing him as the 68th wealthiest individual in the United States according to Forbes.

Philanthropic activities

Davidson was a leading figure in philanthropy, co-establishing the Pistons/Palace Foundation, which has contributed more than $20 million since its inception in 1989. In collaboration with Detroit's Parks and Recreation Department in 1995, the foundation initiated the PARK Program, aimed at revitalizing neighborhood parks and sports venues.

In 1992, he founded the William Davidson Institute at the University of Michigan's Ross School of Business through a $30 million endowment designed to promote the advancement of market economies worldwide. His overall donations to the business school have surpassed $55 million.

The Council of Michigan Foundations recognized Davidson in 1997 for his philanthropic leadership, and The New York Times listed him among the nation's most generous benefactors. He provided a $2 million renewable gift to the Detroit Symphony Orchestra and pledged $1 million toward cancer research at both the Karmanos Cancer Institute and the Children's Research Center of Michigan.

After the Yom Kippur War, Davidson, alongside philanthropist Lloyd J. Paul, was honored with Israel's Prime Minister's Club Award for exceptional support. In 1999, he made a landmark $20 million donation to establish the Davidson Institute of Science Education at Israel's premier research institution, the Weizmann Institute of Science, marking its largest private contribution at that time. He subsequently added another $15 million to support the institute.

Davidson also endowed the William Davidson Graduate School of Jewish Education at the Jewish Theological Seminary of America with $15 million. The Temple Mount archaeological excavations in Jerusalem bear his name in recognition of his support. His philanthropy extended to backing the American Technion Society in founding an innovative center dedicated to managing technology-driven enterprises at the Technion – Israel Institute of Technology, as well as funding graduate scholarships for Jewish studies through the Wexner Foundation.

In 2007, he reinforced his dedication to healthcare philanthropy by donating $75 million to Jerusalem's Hadassah Ein Kerem Hospital.

Awards and recognition

Davidson received prestigious honors including being named Commander of the Order of the Oak Crown and Grand Officer of the Order of Merit of the Grand Duchy of Luxembourg.

Personal life

Davidson was married four times and fathered two children:

Ethan Daniel Davidson, a musician involved with the William Davidson Foundation, married to fellow musician Gretchen Gonzales.
Marla Davidson Karimipour, wife of Cyrus Karimipour.

His fourth marriage took place in 1995 to Karen Weidman, who embraced Judaism upon their union. She has three daughters from a prior marriage, one being actress Elizabeth Reaser, who has appeared in over 30 films and television productions including the Twilight series.

Commissioned by Davidson in 1988, The Wetsmans: Odyssey of an American Family documents the history of the Wetsman family and is accessible online.

Death

Davidson passed away on March 13, 2009, at age 86 after experiencing prolonged health challenges. His funeral was conducted at Congregation Shaarey Zedek in Southfield, Michigan, followed by burial in Birmingham.

Following his death, his widow Karen inherited ownership of the Detroit Pistons and subsequently sold Palace Sports & Entertainment—including the Pistons—to Platinum Equity founder Tom Gores in 2011 for roughly $325 million.
