USPS Shares the Legacy of Four Distinguished American Scientists
The U.S. Postal Service shares the legacy of four distinguished American scientists with the dedication of its latest FOREVER® stamps. MACtac® supplied the pressure-sensitive adhesive label materials for 30 million, 44-cent first-class stamps issued.
The stamps celebrate American scientists’ commitment to understanding the fundamental process of nature and their contributions to the advancement of science. The stamps were designed by art director Ethel Kessler and designer, typographer and photo illustrator Greg Berger. They worked together to create a collage featuring a photograph, a signature and items such as equations and diagrams associated with each scientist’s research.
“MACtac is happy to be a part of the celebration honoring American scientists,” said Allison Hazel, marketing manager, MACtac Printing Products. “Science is important in our everyday lives, and the hard work of scientists often times goes unrecognized. By acknowledging their contributions, we hope to inspire another generation of scientists to continue to fuel advances.”
The stamp issuance honors chemist Melvin Calvin; botanist Asa Gray; physicist Maria Goeppert Mayer; and biochemist Severo Ochoa. They were recognized by Pritha Mehra, USPS vice president, mail entry and payment technology, at a special ceremony at the Science Museum of Minnesota on June 16, 2011. The ceremony enabled the USPS to share the stories of each of the scientists. Their contributions and achievements include the following:
Melvin Calvin was the first scientist to trace in detail the process of photosynthesis, and he conducted pioneering research on using plants as an alternative energy source. He won the Nobel Prize in chemistry in 1961.
Asa Gray, one of the first professional botanists in the United States, advanced the specialized field of plant geography and became the principal American advocate of evolutionary theory in the mid-nineteenth century.
Maria Goeppert Mayer developed a theoretical model that helped explain the structure of the atomic nucleus; for this work she became one of only two women, the other Marie Curie, to win a Nobel Prize in physics.
Severo Ochoa, a biochemist, was the first scientist to synthesize ribonucleic acid, and he competed in the race to decipher the genetic code. Ochoa won the Nobel Prize in physiology of medicine in 1959.
The American Scientists stamps are the third in the American Scientist series issued by the USPS. The first series was issued in 2005 and featured geneticist Barbara McClintock, thermodynamicist Josiah Willard Gibbs, mathematician John von Neumann and physicist Richard Feynman. The second series was issued in 2008 and included physicist John Bardeen, biochemist Gerty Cori, astronomer Edwin Hubble and structural chemist Linus Pauling.
The stamps celebrating American scientists are FOREVER stamps and are available as a pane of 20 stamps, a block of 10 stamps, or a block of four stamps. Stamps may be purchased at local post offices, at the postal store website at www.usps.com/shop, or by calling 800-STAMP-24.
