Question: Who was born earlier, Robert Bunsen or Gustav Kirchhoff?
Context: In fluid dynamics, the Kirchhoff equations, named after Gustav Kirchhoff, describe the motion of a rigid body in an ideal fluid. Gustav Robert Kirchhoff (] ; 12 March 1824 – 17 October 1887) was a German physicist who contributed to the fundamental understanding of electrical circuits, spectroscopy, and the emission of black-body radiation by heated objects. Kirchhoff's circuit laws are two equalities that deal with the current and potential difference (commonly known as voltage) in the lumped element model of electrical circuits.  They were first described in 1845 by German physicist Gustav Kirchhoff.  This generalized the work of Georg Ohm and preceded the work of Maxwell.  Widely used in electrical engineering, they are also called Kirchhoff's rules or simply Kirchhoff's laws. There are several Kirchhoff's laws, all named after Gustav Kirchhoff: Bunsen Peak el.  8564 ft is a prominent peak due south of Mammoth Hot Springs in Yellowstone National Park, Wyoming.  The peak lies on the east flank of Kingman Pass on the Mammoth to Norris section of the Grand Loop Road.  The peak was first ascended by Ferdinand V. Hayden and Captain John W. Barlow in 1871, Bunsen Peak was not named until 1872 during the second Hayden Geologic Survey.  E. S. Topping named the peak "Observation Mountain" in 1872 as well, but that name did not stick.  The Bunsen Peak Trail with its trailhead just south of Mammoth is a steep 2.1 mi to the summit.  Bunsen Peak was named for the German chemist Robert Bunsen, the inventor of the Bunsen Burner and responsible for early work on volcanic geyser theories. In the mathematical field of graph theory, Kirchhoff's theorem or Kirchhoff's matrix tree theorem named after Gustav Kirchhoff is a theorem about the number of spanning trees in a graph, showing that this number can be computed in polynomial time as the determinant of a matrix derived from the graph.  It is a generalization of Cayley's formula which provides the number of spanning trees in a complete graph. The Bunsen–Kirchhoff Award is a prize for "outstanding achievements" in the field of analytical spectroscopy.  It has been awarded since 1990 by the German Working Group for Applied Spectroscopy, and is endowed with by PerkinElmer, Germany.  The prize is named in honor of chemist Robert Bunsen and physicist Gustav Kirchhoff. Dr. Bunsen Honeydew is a Muppet character from "The Muppet Show", performed by Dave Goelz.  He is a bald, green-skinned, bespectacled, lab-coated scientist who would do periodic science segments from "Muppet Labs, where the future is being made today."  The character has no eyes, only completely transparent, lensless glasses, giving the appearance of a stereotypical absent-minded intellectual.  His first name is derived from Robert Bunsen, after whom the Bunsen Burner was named.  His last name is a reference to the honeydew melon, which his head is virtually shaped like.  It is also a reference to Honeywell Labs, a technology company which aired TV commercials (""That someday is today ... at Honeywell"") well-known at the time of the original Muppet Show. Peter Desaga was a German instrument maker at the University of Heidelberg who worked with Robert Wilhelm Bunsen.  In 1855, Desaga perfected an earlier design of the laboratory burner by Michael Faraday into the Bunsen burner.  The Desaga family held the right to market the burner for generations, as part of an agreement made with Bunsen.  The Bunsen burner was essential to the invention of the spectroscope by Robert Wilhelm Bunsen and Gustav Robert Georg Kirchhoff. Robert Wilhelm Eberhard Bunsen ( ; ] ; 30 March 1811 – 16 August 1899) was a German chemist.  He investigated emission spectra of heated elements, and discovered caesium (in 1860) and rubidium (in 1861) with the physicist Gustav Kirchhoff.  Bunsen developed several gas-analytical methods, was a pioneer in photochemistry, and did early work in the field of organoarsenic chemistry.  With his laboratory assistant, Peter Desaga, he developed the Bunsen burner, an improvement on the laboratory burners then in use.  The Bunsen–Kirchhoff Award for spectroscopy is named after Bunsen and Kirchhoff.
