February 14

Herbert Aaron Hauptman was born on February 14, 1917. He was an American mathematician and Nobel laureate. He pioneered and developed a mathematical method that has changed the whole field of chemistry and opened a new era in research in determination of molecular structures of crystallized materials. 



                                                                                Works

Hauptman has authored over 170 publications, including journal articles, research papers, chapters and books. In 1970, Hauptman joined the crystallographic group of the Hauptman-Woodward Medical Research Institute (formerly the Medical Foundation of Buffalo) of which he became Research Director in 1972. Until his death, he served as President of the Hauptman-Woodward Medical Research Institute as well as Research Professor in the Department of Biophysical Sciences and Adjunct Professor in the Department of Computer Science at the University at Buffalo. Prior to coming to Buffalo, he worked as a mathematician and supervisor in various departments at the Naval Research Laboratory from 1947. He received his B.S. from City College of New York, M.S. from Columbia University and Ph.D. from the University of Maryland, College Park.

  1. As for his life, we should know that he was born in New York City, the oldest child of Leah (Rosenfeld) and Israel Hauptman. He was married to Edith Citrynell since November 10, 1940, with two daughters, Barbara (1947) and Carol (1950).

    He was interested in science and mathematics from an early age which he pursued at Townsend Harris High School, graduated from the City College of New York (1937) and obtained an M.A. degree in mathematics from Columbia University in 1939.

    After the war he started a collaboration with Jerome Karle at the Naval Research Laboratory in Washington, D.C. and at the same time enrolled in the Ph.D. program at the University of Maryland, College Park. This combination of mathematics and physical chemistry expertise enabled them to tackle head-on the phase problem of X-ray crystallography. By 1955 he had received his Ph.D. in mathematics, and they had laid the foundations of the direct methods in X-ray crystallography. Their 1953 monograph, "Solution of the Phase Problem I. The Centrosymmetric Crystal", contained the main ideas, the most important of which was the introduction of probabilistic methods through a development of the Sayre equation.

    In 1970 he joined the crystallographic group of the Medical Foundation of Buffalo of which he was Research Director in 1972. During the early years of this period he formulated the neighborhood principle and extension concept. These theories were further developed during the following decades.

    In 2003 he was one of 21 Nobel Laureates who signed the Humanist Manifesto.

  2. The statehood day!

    Arizona is a U.S. state located in the southwestern region of the United States. Arizona is also part of the Western United States and of the Mountain West states. Arizona is the sixth most extensive and the 15th most populous of the 50 states. Its capital and largest city is Phoenix.Arizona is the 48th state and last of the contiguous states to be admitted to the Union, and it achieved statehood on February 14, 1912.

  3. The statehood day of one more U.S. state. Maybe at this day (St. Valentines Day) people were very friendly and peaceful that signed so many important papers ;)

    Oregon is a state in the Pacific Northwest region of the United States. It is located on the Pacific coast, with Washington to the north, California to the south, Nevada on the southeast and Idaho to the east. The Columbia and Snake rivers delineate much of Oregon's northern and eastern boundaries, respectively. The area was inhabited by many indigenous tribes before the arrival of traders, explorers, and settlers who formed an autonomous government in Oregon Country in 1843. The Oregon Territory was created in 1848, and Oregon became the 33rd state on February 14, 1859.
