American Crystallographic Association (ACA)

What is the ACA?

This is what its website (ACA Home (amercrystalassn.org)) says about the ACA:

"The American Crystallographic Association, Inc. (ACA) is a non-profit, scientific organization of over a thousand members in more than thirty-five countries. The ACA was founded in 1949 through a merger of the American Society for X-Ray and Electron Diffraction (ASXRED) and the Crystallographic Society of America (CSA). The objective of the ACA is to promote interactions among scientists who study the structure of matter at atomic (or near atomic) resolution. These interactions will advance experimental and computational aspects of crystallography and diffraction. Understanding the nature of the forces that both control and result from the molecular and atomic arrangements in matter will help shed light on chemical interactions in nature."

American Crystallographic Association

The most prestigious, international crystallographic association, boasting more than 40 Nobel Prize Laureates and over 1,300 members from 37 countries worldwide.

The ACA is especially famously known for its numerous Nobel Prize Laureates ((IUCr) Nobel Prize winners), many of which attained their recognition through extensive research in crystallography-related fields of science:
