Innovations and Advancements in Heat & Mass Transfer: Celebrating the Legacy of Professor Ephraim M. Sparrow

The passing of Professor Ephraim M. Sparrow on August 1, 2019 left a large void in the worldwide heat and mass transfer community. To many in the field, he was an intellectual giant, who famously was the "most cited" mechanical engineering professor in the Science Citation Index for many decades. Many scholars, young and old, have encountered Professor Sparrow's multitude of works over a wide range of topics in standard academic textbooks, reference books, and eminent heat transfer journals. To his colleagues and students, 'Eph' was more than a giant in the field of heat transfer, he was an incredible mentor and a lifelong friend who was passionate about the multifaceted area of thermal science and never stopped wanting to learn. To celebrate Eph's multitude of contributions, a memorial symposium was held at the University of Minnesota, where he had spent his entire professional academic career.
