The Cambridge community is deeply mourning the passing of Andrew “Andy” Engelward, a respected educator whose influence touched family, friends, colleagues, and countless students. His dedication to teaching and innovation left a lasting mark on mathematics education.
Professor Engelward, a cherished instructor at Harvard Extension School, devoted his life to helping students understand mathematics through mentorship, creativity, and forward-thinking educational strategies. His loss creates a significant void within both the academic and educational communities.
Andy was admired for his charm, enthusiasm, and extraordinary passion for teaching. He had an exceptional talent for simplifying difficult mathematical concepts, making them accessible through inventive demonstrations, props, and hands-on learning techniques.
One of his most recognized contributions was the creation of large-scale visual reliefs used to explain functions of two variables. These visual tools transformed abstract concepts into tangible, intuitive learning experiences that inspired students and educators alike.
Andy was also ahead of his time in integrating technology into the classroom. He was among the first to introduce Webwork into his Math X—now Math M—courses. This early adoption helped pave the way for what would later evolve into the interactive learning platform Edfinity, a widely used system for structured, problem-based mathematics education.
Beyond his instructional creativity, Andy served as a trusted mentor. He authored the original “preceptor book,” a valuable guide that supported new instructors and preceptors for more than a decade. His insight helped colleagues manage the many responsibilities associated with teaching, administration, and technology integration, creating a supportive environment for professional growth.
Colleagues remember him as an encouraging, compassionate leader who readily shared strategies, offered advice, and supported new educators. His leadership played a key role in creating the Math for Teaching program at Harvard Extension School, providing structured opportunities for future educators to gain confidence and develop practical classroom skills.
As educational methods evolved—from traditional classroom teaching to hybrid and online formats—Andy remained a steady source of guidance. He was among the earliest to adopt Zoom and hybrid instruction, ensuring students could continue receiving high-quality education during periods of transition and challenge.
His dedication, innovation, and mentorship will be remembered by all who had the privilege of learning from him or working alongside him.
