I discovered Amos work through his creation of Cellosaurus. I remain in awe of the work that went into this ressource and how impactful it is to those of us who have developed cell line models. My first correspondence with identified Amos as a kind individual who cared greatly for precision and accuracy. As a member of the science community I thank him for all the excellent ressources he provided throughout his career. While I am saddened to hear of his passing, his work will continue to guide scientific advances for decades to come. My greatest sympathies to his family and friends.
