Walsh Jesuit High School was funded by a generous gift from Cornelius Walsh (b. 1864), a prominent industrialist and Catholic layman who had lived his entire life in Cuyahoga Falls. Upon his death in 1932, Cornelius bequeathed his entire fortune to his wife, Jane, who continued to donate generously to Catholic institutions and, with the assistance of her nephew, William A. Walsh, designed her will to include a large gift for the foundation of a Catholic high school. William, partial to the Jesuits, convinced his aunt to bequeath to the Society of Jesus her property and $100,000 for the building of an all-boys school that would be a memorial to her husband. William approached the Chicago Province of the Jesuits with the proposal, but the gift lay dormant for years until found during a transfer of files from the Chicago Province to the Detroit Province in 1959. William urged Fr. John McGrail, S.J., the head of the Jesuits' Detroit Province, to reconsider the proposal made in Jane's will. The school's campus was originally planned to be built in downtown Cuyahoga Falls near St. Joseph Parish School, but using the gift from Jane (which had grown to $2 million under William's stewardship, and to which the Cleveland Catholic Diocese added $1 million), 50 acres were purchased from the Conway family farm north of downtown, with an additional 50 acres purchased later. Groundbreaking ceremonies for Walsh Jesuit took place in 1964, and the school opened its doors to 153 freshmen on September 7, 1965. The school was dedicated in May 1966, and the first class graduated in 1969. Initially founded as an all-boys institution similar to other prominent
Northeast Ohio Catholic high schools, Walsh Jesuit's leadership decided to go co-ed in 1991 amid excess capacity and financial challenges to the school's continued existence. The decision was initially met with resistance by many Walsh Jesuit alumni and students, culminating in a student
walkout, which received extensive local media coverage, when the news of the decision was made public. Despite the protests, the first girls entered the school at the beginning of the 1993–1994 academic year, and currently constitute approximately half of the overall student population. ==Athletics==
