Abraham Pais (May 19, 1918 – July 28, 2000) was a Dutch-born American physicist and science historian. Pais earned his Ph.D. from University of Utrecht just prior to a Nazi ban on Jewish participation in Dutch universities during World War II. When the Nazis began the forced relocation of Dutch Jews, he went into hiding, but was later arrested and saved only by the end of the war. He then served as an assistant to Niels Bohr in Denmark and was later a colleague of Albert Einstein at the Institute for Advanced Study in Princeton, New Jersey. Pais wrote books documenting the lives of these two great physicists and the contributions they and others made to modern physics. He was a physics professor at Rockefeller University until his retirement.
Pais was born in Amsterdam, the first child of middle-class Dutch Jewish parents. His father, Isaiah "Jacques" Pais, was the descendant of Sephardic Jews who migrated from Portugal to the Low Countries around the beginning of the 17th century. His mother, Kaatje "Cato" van Kleeff, was the daughter of an Ashkenazi diamond cutter. His parents met while studying to become elementary-school teachers. They both taught school until his mother quit when they married on December 2, 1916. His only sibling, Annie, was born on November 1, 1920. During Pais's childhood his father was an elementary schoolmaster, headmaster, and later the headmaster of the Sephardic Hebrew school.
Abraham is a saint of the Ethiopian Orthodox Tewahedo Church. His feast day is celebrated May 5.
Sapor of Bet-Nicator (also known as Shapur of Bet-Nicator) was the Christian bishop of Bet-Nicator.
He was reported with 4 companions to King Shapur II, on the basis of their having preached against the Zoroastrian religion. After being subjected to prolonged torture, Bishop Sapor died in prison on November 20, 339.
His companions in martyrdom included Abraham.
There is no record of a feast day for these individuals.
Abraham figures prominently in Catholic liturgy. Of all the names of the Old Testament used in the liturgies of the Roman Rite, a special prominence accrues to those of Abel, Melchisedech, and Abraham through their association with the idea of sacrifice and their employment in this connection in the most solemn part of the Canon of the Mass. Abraham's name occurs so often and in such a variety of connections as to give him, among Old Testament figures, a position of eminence in the liturgy, perhaps surpassed by David alone.
