When was the tobacco mosaic virus successfully crystallized?

Explanation

The tobacco mosaic virus (TMV) was first successfully crystallized in 1935 by the American biochemist Wendell Meredith Stanley.This work was groundbreaking because it showed that viruses could be isolated and crystallized like chemicals, which challenged the prevailing view of viruses as "living organisms" and helped establish virology as a scientific field. Stanley was awarded the 1946 Nobel Prize in Chemistry for this achievement.
