Víctor Manuel Blanco

Blanco died on March 8, 2011 at Indian River Medical Center in Vero Beach, Florida. He was survived by his wife of 42 years, Betty Blanco; a son, Daniel Blanco; a stepson, David Mintz; and a stepdaughter, Elizabeth Vitell.

Asteroid 9550 Victorblanco, discovered by American astronomer Edward Bowell at the Anderson Mesa Station in Arizona in 1985, was named in his honor. The official naming citation was published by the Minor Planet Center on 9 March 2001 (M.P.C. 42359). This main-belt asteroid measures approximately 12 kilometers in diameter and belongs to the main belt's background population.

On 8 September 1995, in a well-attended mountaintop ceremony, the CTIO 4-m telescope was officially named the Víctor M. Blanco Telescope, also known as "The Blanco 4m." Amongst its many uses, this telescope is used to study cosmic acceleration - the possibility that our universe is expanding at an accelerating rate. At the main entrance to the building a large bronze plaque reads, in both Spanish and English (see adjunct box).

As director of CTIO, Blanco also maintained excellent relations with the Chilean astronomical community and the Chilean public at large. His tenure spanned the presidencies of Eduardo Frei Montalva, Salvador Allende, and Augusto Pinochet. Blanco was director of CTIO until 1981, when he was succeeded by Osmer.

In addition to these university installations, Blanco played a central role in persuading various agencies to participate in the construction of a four-meter telescope. During its construction, Blanco personally oversaw the alignment and calibration of the telescope. The telescope, which is the southern twin of the four-meter instrument at Kitt Peak National Observatory, opened in 1974. This four-meter telescope (also known as a "4-m") became the most productive telescope in the Southern Hemisphere.

In July 1967, Blanco became the second director of the Cerro Tololo Inter-American Observatory (CTIO). Located in Cerro Tololo mountain, Chile and founded in 1963, it is part of the National (U.S.) Optical Astronomy Observatory known as "NOAO." Blanco assembled the scientific, engineering, and technical staff from scratch.

When Blanco arrived at CTIO, there was a 60-inch telescope in operation. During his tenure the University of Michigan's 0.6-m Curtis Schmidt moved there in 1967, CTIO installed a 0.9-m reflector in 1967 and a 1.5-m reflector in 1968, and Yale University's 1-m reflector was installed there in 1973.

In 1959, while serving as a professor of astrophysics at the Case Institute of Technology (renamed Case Western Reserve University in 1967) in Cleveland, Ohio, Blanco discovered an open cluster. It was named Blanco 1 in his honor, and is centered on the blue star Zeta Sculptoris. According to The Monthly Notices of the Royal Astronomical Society, Blanco 1 exhibits subsolar ratios that are not observed among nearby field stars. Together with his wife Betty, Blanco and Martin McCarthy conducted pioneering research into the stellar population in the central regions of our galaxy, and in the Magellanic Clouds. They discovered the change in the ratio of carbon stars to M-type stars from the nuclear bulge of our galaxy, in relation to both Large Magellanic Clouds and Small Magellanic Clouds.

Blanco was employed by the University of Puerto Rico as an assistant professor of astrometry, until he was recruited in 1948 to assist in polishing, calibrating and maintaining the mirrors of the 200-inch Hale telescope in California. He entered the University of California, Berkeley, where he continued his studies and earned his master's degree and, in 1949, his Doctorate in astronomy. In 1949, he returned to Puerto Rico and reassumed his duties at the University of Puerto Rico.

Víctor Manuel Blanco (March 10, 1918 – March 8, 2011) was a Puerto Rican astronomer who in 1959 discovered Blanco 1, a galactic cluster. Blanco was the second Director of the Cerro Tololo Inter-American Observatory in Chile, which had the largest telescope in the Southern Hemisphere at the time. In 1995, the 4-meter telescope was dedicated in his honor and named the Víctor M. Blanco Telescope; it is also known as the "Blanco 4m."
