A tribute to a man of science: lessons from Professor Luiz R. Travassos (1938-2020).

Luiz Rodolpho Raja Gabaglia Travassos, MD, PhD was a world-class microbiologist and cell biologist whose contributions to science were remarkable at multiple levels and across diverse fields. Besides being responsible for the creation of a scientific school that contributed to the transmission of multidisciplinary knowledge through several generations in Brazil and abroad, Professor Travassos was a pioneer in the fields of Microbiology, Glycobiology, Mycology, Parasitology, and Cancer Biology. To fully measure his contribution to science is an impossible task. We, some of his former students, post-docs, and collaborators, will illustrate the joy of having Professor Travassos as a mentor and friend through highlighting some of his breakthroughs in the fields of microbial physiology, infection, and cancer biology immersed in backstage stories of how he influenced so many people in many aspects of life. We hope that our future scientific generations and all who are passionate about discovery will see Travassos as an inspiration and example of a love for science.
