K. Anders Ericsson, PhD, was one of the world’s preeminent experts on expertise and passed away in June of 2020. He is survived by his wife, Natalie Sachs-Ericsson, his children, Lina and Jens Ericsson, and his grandson, Jakob.

Ericsson’s passion for understanding skill acquisition processes, particularly the role of deliberate practice, led to the widespread use of the expert performance approach. It emphasizes the importance of understanding the mental processes and knowledge that differentiates experts from lesser performers and spurred investigations in many domains, particularly in sports and medicine. He contributed to the development of better process tracing techniques to fully understand skill acquisition, including the analysis of concurrent and retrospective think-aloud verbal protocols gathered during problem solving on representative domain tasks.

The K. Anders Ericsson Dissertation Research Grant has been established in his memory.
