Samuel Pierpont Langley (/ˈlæŋli/; August 22, 1834 – February 27, 1906) was an American astronomer, physicist, inventor of the bolometer and pioneer of aviation. He attended Boston Latin School, graduated from English High School of Boston, was an assistant in the Harvard College Observatory, then moved to a job ostensibly as a professor of mathematics at the United States Naval Academy, but actually was sent there to restore the Academy's small observatory. In 1867, he became the director of the Allegheny Observatory and a professor of astronomy at the Western University of Pennsylvania, now known as the University of Pittsburgh, a post he kept until 1891 even while he became the third Secretary of the Smithsonian Institution in 1887. Langley was the founder of the Smithsonian Astrophysical Observatory.
Langley arrived in Pittsburgh in 1867 to become the first director of the Allegheny Observatory, after the institution had fallen into hard times and been given to the Western University of Pennsylvania. By then, the department was in disarray – equipment was broken, there was no library and the building needed repairs. Through the friendship and aid of William Thaw, a Pittsburgh industrial leader, Langley was able to improve the observatory equipment and build additional apparati. One of the new instruments was a small transit telescope used to observe the position of the stars as they cross the celestial meridian. He raised money for the department in large part by distributing standard time to cities and railroads. Up until then, correct time had only occasionally been sent from American observatories for public use. Clocks were manually wound in those days and time tended to be imprecise. Exact time had not been especially necessary. It was enough to know that at noon the sun was directly above the head. All that until railroad tracks were installed.
Samuel (/ˈsæm.juː.əl/;Hebrew: שְׁמוּאֵל, Modern Shmu'el, Tiberian Šəmûʼēl; Arabic: صموئيل Ṣamuil; Greek: Σαμουήλ Samouēl; Latin: Samvel; Strong's: Shemuwel), literally meaning "Name of God" in Hebrew, is a leader of ancient Israel in the Books of Samuel in the Hebrew Bible. He is also known as a prophet and is mentioned in the second chapter of the Qur'an, although not by name.
His status, as viewed by rabbinical literature, is that he was the last of the Hebrew Judges and the first of the major prophets who began to prophesy inside the Land of Israel. He was thus at the cusp between two eras. According to the text of the Books of Samuel, he also anointed the first two kings of the Kingdom of Israel: Saul and David.
Samuel's mother was Hannah and his father was Elkanah. Elkanah lived at Rama-thaim in the district of Zuph. His genealogy is also found in a pedigree of the Kohathites (1 Chron. 6:3-15) and in that of Heman, his great-grandson (ib. vi. 18-22). According to the genealogical tables, Elkanah was a Levite - a fact otherwise not mentioned in the books of Samuel. The fact that Elkanah, a Levite, was denominated an Ephraimite is analogous to the designation of a Levite belonging to Judah (Judges 17:7, for example).
Samuel (Սամվել Samvel) is an 1886 Armenian language novel by the novelist Raffi. Considered by some critics his most successful work, the plot centres on the killing of the fourth-century Prince Vahan Mamikonian and his wife by their son Samuel.
Samuel of Nehardea or Samuel bar Abba (Hebrew: שמואל or שמואל ירחינאה) was a Jewish Talmudist who lived in Babylonia, known as an Amora of the first generation; son of Abba bar Abba and head of the Yeshiva at Nehardea. He was a teacher of halakha, judge, physician, and astronomer. He was born about 165 CE at Nehardea, in Babylonia and died there about 257 CE. As in the case of many other great men, a number of legendary stories are connected with his birth (comp. Halakot Gedolot, Giṭṭin, end; Tos. Ḳid. 73a s.v. Mai Ikka). In Talmudic texts, Samuel is frequently associated with Abba Arika, with whom he debated on many major issues. He was the teacher of Rabbi Judah ben Ezekiel. From the little biographical information gleaned from the Talmud, we know that Samuel was never ordained as a Tanna, that he was very precise with his words (Kidd. 70), and that he had a special affinity for astronomy: one of his best known sayings was that "The paths of heaven are as clear to me as the pathways of Nehardea."
