  • Bernard Ferdinand Lyot (February 27, 1897 – April 2, 1952) was a French astronomer. He earned a reputation of being an expert of polarized and monochromatic light. Throughout the 1930's, he labored to perfect the coronagraph, which he invented to observe the corona without having to wait for a solar eclipse. In 1938, he showed a movie of the corona in action to the International Astronomical Union.
  • Name originally proposed by Wilkins and Moore for Ptolemaeus A, but not approved by the IAU. The name was shifted to the present crater in the Rectified Lunar Atlas (1963) (Whitaker, 1999, p235). New nomenclature approved by IAU in 1964.
  • Dorsum Lyot is an unofficial name from D.Caes for the wrinkle ridge on the floor of Lyot.
