Chien-Shiung Wu Forever Stamps, 2021 Sheet – Cards, Letters and Stamp Collecting

The spelling of Wu’s name on the stamp reflects how she wrote her own name and referred to herself. It is also how she was known to the scientific community at large. This Romanized spelling of her name is based on the Wade-Giles system, which is all but obsolete for Chinese words and names. The Pinyin system of phonetic notation for Chinese characters is now the standard in both China and the United States.

Art director Ethel Kessler designed the stamp with original art by Kam Mak.
