Professor Louis "Lou" Block

In Loving Memory of Professor Louis “Lou” Block (1947–2026) We are heartbroken to share that University of Florida Professor Emeritus Louis (“Lou”) Block passed away on January 15, 2026. He was the kindest person we have ever known – brilliant, patient, and unfailingly generous with his time and his heart. He was deeply loved and widely admired by family, friends, students, and colleagues alike. Born in New York City in 1947, Lou moved to Miami, Florida, as a boy and soon began a lifelong love of learning and problem solving. He earned his Bachelor’s degree from the University of Florida in 1969 and his Ph.D. in mathematics from Northwestern University in 1973. He then returned to UF, where he served as a Professor of Mathematics until his retirement in 2021, becoming a constant, steady presence on campus for nearly five decades. A distinguished scholar in dynamical systems and topology, Lou authored more than 50 research articles, many in leading journals such as Transactions of the American Mathematical Society. He was a trusted collaborator and a generous intellectual partner, twice serving as a Van Vleck Visiting Professor at Wesleyan University and as a regular Visiting Fellow at the Australian National University. His research received support from the National Science Foundation and DARPA, and he delivered more than 80 invited lectures across the United States and in countries including Australia, China, and Germany. During his 48 years at UF, Lou was the instructor students hoped to find on their schedules – clear, compassionate, and committed to helping others succeed. He taught undergraduates and graduate students with equal care, directed four Ph.D. students, and earned a TIP Teaching Award in 1994 in recognition of his excellence in the classroom. Beyond teaching and research, he served the department with dedication, including as Graduate Coordinator and Associate Chair of Graduate Studies. A lifelong Gator and avid sports fan, Lou was often seen wearing the orange and blue at UF football, baseball, and other Gator sporting events – usually in the company of those he loved. He was an active member of the Gainesville 300 Club, where he played tennis and pickleball, and some of his happiest moments were on the courts with his grandchildren. Lou was a regular at his daughter Jenny’s cycling classes at Gainesville Health & Fitness, where he brought his characteristic encouragement and steady determination, earning the affection of both his instructor and his classmates. He was also an excellent bridge player and part of a long standing group that included several fellow math faculty members. A Gentle Heart, A Brilliant Mind Those who knew Lou speak first of his character: his extraordinary kindness, his patience that made others feel at ease, and his formidable intellect worn with humility. He listened closely, taught generously, and showed up – reliably and quietly – for the people around him. He made the world better in countless small ways that added up to a remarkable life of meaning. Family Lou’s greatest pride and deepest joy was his family, who loved him so very much. He is survived by his wife, Linda Lingo; his children, Jenny Frazer and Rachel Reid; his grandchildren, Jake, Ryan, Alexis, Lauren, Jacob, Jonathan, Madison, Hannah, Jay, and Miles; and his great grandchild, Charlotte. He is also survived by his sister, Idelle Newburge. Lou is affectionately remembered by his former spouse, Candy Pigott, mother of Jenny and Rachel, and by many others through his and Linda’s blended family, all of whom were embraced fully by Lou’s generous heart. He will be sorely missed and lovingly remembered. Celebration of Life will be held Sunday, January 25, 2026 at 12:00 p.m. Prairie Creek Conservation Cemetery, 7204 SE County Road 234 Gainesville, with Rabbi Jonah Zinn officiating. A reception will follow at Oak Hammock (Acorn Room) 5100 SW 25th Blvd., Gainesville from 1:00 pm – 4:00 pm. In honor of Lou’s lifelong commitment to learning and to supporting others, his family is establishing the Lou Block Memorial Scholarship Fund. In lieu of flowers, donations may be made to the Frazer Foundation for the Lou Block Memorial Scholarship Fund.
