History

For nearly 200 years, William H. Sadlier, Inc. has been forming K-12 students in the Catholic faith and preparing them for academic success by offering a variety of educational materials in print and digital formats.

Leading one of the few family businesses of its age, the Sadlier family proudly continues to nurture the vision of founders, Denis and James Sadlier, with integrity, creativity, and an unwavering commitment to educational publishing.

The Sadlier story is one of triumph, through generations of one family's perseverance and dedication to a singular vision of service and excellence.

In 1832, brothers Denis and James Sadlier, Irish immigrants who settled in New York, began publishing materials to meet the spiritual and educational needs of the Irish immigrant community. Mary Anne Madden Sadlier, the wife of James, was one of the primary contributors to the editorial work of the company, D & J Sadlier. In 1895, she was awarded the distinguished Laetare Medal from the University of Notre Dame for her prolific work as a novelist. Their nephew William H. Sadlier worked with his uncles for several years and in 1872 launched his own eponymous publishing firm, which later merged with the business Denis and James had founded to become the venerable publishing company Sadlier is today.

Sadlier owes its longevity to very strong, business-minded women, including Annie Cassidy Sadlier, the wife of William H. Sadlier. After the sudden death of her husband in 1877, Annie successfully petitioned the New York State legislature to pass a special bill allowing her to run the company in her late husband's name. At the time she became president of Sadlier, she was a 26-year-old widow expecting her third child. Believing in the company's potential, she used her husband's life insurance payment to sustain and grow the business.

Their son Frank Sadlier, who eventually assumed leadership of the company, was responsible for seeing Sadlier through the Great Depression with best-selling titles, including Social Geography, and by creating Catholic education workbooks at a time when Catholic schools couldn't afford costly textbooks. Neva Hecker Sadlier, Frank's wife, was a prolific Catholic author and a long serving Chair of the Board of Sadlier.

In 1972 under the leadership of F. Sadlier Dinger, then Chairman of the Board and the only grandchild of William and Annie, Sadlier acquired Oxford Book Company, and achieved its mission of publishing books across several academic disciplines. During his tenure F. Sadlier Dinger mentored and groomed his two sons, Frank and William, for future roles at the company.

For 25 years, brothers Frank Sadlier Dinger and the late William Sadlier Dinger, fondly known as Ding and Bill, led the company through a period of growth.  Both retired in 2018 and Ding continues to serve as the Chairman of the Board. The current leadership team includes sixth-generation family members Melissa Dinger Gibbons, Director of Customer Service; William Sadlier Dinger, Jr., Group Vice President; and Angela Dinger, Senior Vice President and General Counsel.

For nearly two centuries, the downtown New York City-based company has thrived. Employees beyond the family, such as Frank Power and Dr. Elinor R. Ford, serving in roles such as publisher, president, and chief executive officer, enthusiastically adopted Sadlier's ethos and vision to be a leader in education. Raymond D. Fagan, who has been at the company since 2012, was appointed President and Chief Executive Officer in 2017.

Pioneers in engaging students in their faith and developing groundbreaking curriculum across academic disciplines, the founders' entrepreneurial spirit lives on in the generations of family and employees who have dedicated themselves to the success of the company.

Today, Sadlier utilizes technology and traditional resources to provide parishes and Catholic, private, and public schools with materials that help educators and students achieve academic success-across the U.S. and internationally. Looking to the future, Ray's leadership joined with an experienced executive team that includes several family members will continue to guide Sadlier toward a third century of innovation and growth.
