Английский астроном и оптик (р.1612?). Первым обнаружил, что телескоп можно использовать не только для обзора неба, но и в качестве измерительного инструмента. Первым сделал телескоп с двумя выпуклыми линзами (до него была известна только схема Галилея). Письма, опубликованные много лет спустя, показывают, что он изготовил микрометр с перекрестными нитями. Гюйгенс позднее независимо от него сделал микрометр худшего качества (1658). Погиб в сражении. КИА.

Gascoigne, William
1. Dates
Died: battle of Marston Moor, Yorkshire, 2 July 1644
Dateinfo: 32

2. Father
Occupation: Gentry
Henry Gascoigne was a member of the gentry.
Clearly prosperous.

3. Nationality
Birth: English
Career: English
Death: English

4. Education Schooling: Oxford Although there is no record of higher education, Gascoigne himself testified to study at Oxford. Like Horrocks at Cambridge, he found Oxford "desti
tute of mathematical learning."

5. Religion Affiliation: Catholic There does not seem to be any explicit record. However, his father was apparently Catholic. One story about him related him to Jesuits. And his papers passed into the hands of the prominent Yorkshire Catholic family, the Towneleys. I don't feel any serious doubt that Gascoigne was Catholic.

6. Scientific Disciplines Primary: Astronomy, Optics, Instrumentation As an observer, Gascoigne found Lansberg's tables in error, and this led him to give serious attention to issues of observational accuracy. In keeping with his interest in observational instruments, he was said to have a treatise of optics ready for the press, and an essay on optics did
survive to be printed by Rigaud. He contributed greatly to instrumentation. He is asserted to have been the first to make a telescope with two convex lenses. (A telescope, which survives, that he did make in late 1640 was a Galilean type.) He invented methods of grinding glasses. Most important, he developed the first microme
ter. He applied the telescope to the quadrant.

7. Means of Support
Primary: Per He Inherited Wealth.

8. Patronage Type: None I have not found any indications of it, though the details on his life are

9. Technological Involvement Type: Instruments The invention of eyepiece micrometer, using a screw to measure the distance between two wires or plates inside the eyepiece, in order to measure small
angles with precision.

The application of the telescope to the quadrant.

A lens grinding machine.

10. Scientific Societies Memberships: None Informal Connections: Correspondence with J. Horrocks, W. Crabtree, W. Oughtred, and Christopher Towneley.
