Cleveland Abbe (December 3, 1838 – October 28, 1916) was an American meteorologist and advocate of time zones.

While director of the Cincinnati Observatory in Cincinnati, Ohio, he developed a system of telegraphic weather reports, daily weather maps, and weather forecasts. In 1870, Congress established the U.S. Weather Bureau and inaugurated the use of daily weather forecasts. In recognition of his work, Abbe, who was often referred to as “Old Probability” for the reliability of his forecasts, was appointed the first head of the new service, and is considered the father of the National Weather Service.

Charles David Allis (born March 22, 1951) is an American molecular biologist, and is currently the Joy and Jack Fishman Professor and Head of the Laboratory of Chromatin Biology and Epigenetics at The Rockefeller University. In pursuit of understanding the DNAhistone protein complex and the intricate system which allows for gene activation, the Allis lab focuses on chromatin signaling via histone modifications – acetylation, methylation and phosphorylation. Allis is best known for deciphering regulatory mechanisms that impinge upon the fundamental repeating unit of chromatin and for identifying the responsible enzyme systems that govern the covalent modifications of histone proteins, the principal components that organize chromatin. Allis discovered the critical link, through histone acetyltransferase-containing transcriptional coactivators, between targeted histone acetylation and gene-specific transcriptional activation. In further studies, he linked histone phosphorylation events to mitosis and mitogen action, established a synergy between histone phosphorylation and acetylation events and elaborated the ‘histone code hypothesis’ (and extensions thereof), one of the most highly cited theories governing epigenetics.
Richard Allison (1757 – March 22, 1816) was Physician General of the U.S. Army, the position that later became Surgeon General, from 1792 to 1796. He was the first physician to set up a permanent practice in Cincinnati, Ohio.
Neil Alden Armstrong (August 5, 1930 – August 25, 2012) was an American astronaut and the first person to walk on the Moon. He was also an aerospace engineer, naval aviator, test pilot, and university professor. Before becoming an astronaut, Armstrong was an officer in the U.S. Navy and served in the Korean War. After the war, he earned his bachelor’s degree at Purdue University and served as a test pilot at the National Advisory Committee for Aeronautics (NACA) High-Speed Flight Station, where he logged over 900 flights. He later completed graduate studies at the University of Southern California.

A participant in the U.S. Air Force‘s Man in Space Soonest and X-20 Dyna-Soar human spaceflight programs, Armstrong joined the NASA Astronaut Corps in 1962. He made his first space flight as command pilot of Gemini 8 in March 1966, becoming NASA’s first civilian astronaut to fly in space. He performed the first docking of two spacecraft, with pilot David Scott.[1] This mission was aborted after Armstrong used some of his reentry control fuel to prevent a dangerous spin caused by a stuck thruster, in the first in-flight space emergency.

Armstrong’s second and last spaceflight was as commander of Apollo 11, the first manned Moon landing mission in July 1969. Armstrong and Lunar Module pilot Buzz Aldrin descended to the lunar surface and spent two and a half hours outside the spacecraft, while Michael Collins remained in lunar orbit in the Command/Service Module. Along with Collins and Aldrin, Armstrong was awarded the Presidential Medal of Freedom by President Richard Nixon. President Jimmy Carter presented Armstrong the Congressional Space Medal of Honor in 1978. Armstrong and his former crewmates received the Congressional Gold Medal in 2009.

He accepted a teaching position in the Department of Aerospace Engineering at the University of Cincinnati.

Charles J. Bates (May 4, 1930 – September 28, 2006) was an American food scientist who was involved in the development of baking formulas for angel food and devil’s food cake, while working for Procter & Gamble, then later developed high fructose corn syrup sweetener for Coca-Cola. Away from his research, Bates was also involved with the Boy Scouts of America in Indiana, earning numerous awards.

He secured a state appropriation for its support and that of a hospital.
Eula Bingham was born in Covington, Kentucky, in 1929. She earned a B.S. in 1951 in Chemistry and Biology from Eastern Kentucky University, Richmond, Kentucky; an M.S. in 1954 in Physiology from the University of Cincinnati, Cincinnati, Ohio; and a Ph.D. in 1958 in Zoology, also from the University of Cincinnati, Cincinnati, Ohio.
