Question: What is the birth date of this English scientist, whose laboratory burner design was later perfected by Peter Desaga into the Bunsen burner?
Context: 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. 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. 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. A Meker–Fisher burner, or Meker burner, is a laboratory burner that produces multiple open gas flames, used for heating, sterilization, and combustion.  It is used when laboratory work requires a hotter flame than attainable using a Bunsen burner, or used when a larger-diameter flame is desired, such as with an inoculation loop or in some glassblowing operations.  The burner was introduced by French chemist Georges Méker in an article published in 1905. The Teclu burner is a laboratory gas burner, a variant of the Bunsen burner, named after the Romanian chemist Nicolae Teclu.  It can produce a hotter flame than a Bunsen burner. A Wire gauze is a sheet of thin metal that has net-like crosses or a wire mesh.  Wire gauze is placed on the support ring that is attached to the retort stand between the Bunsen burner and the beakers in order to support the beakers or other glassware or flasks during heating.  Moreover, the glassware has to be flat-bottomed to stay on the wire gauze.  The wire gauze is made of a .  This type of material provides long life expectancy and can be used over and over again without a risk of it being torn.  The sides/corners of the wire gauze are turned inward to help prevent fraying, improve handling and reduce safety risk from protruding ends of wire.  The wire gauze is an important piece of supporting equipment in a laboratory because beakers or any type of glassware cannot be heated directly with a flame from the Bunsen burner, and the wire gauze will help protect the glassware.  There are two types of wire gauze: woven wire gauze and a wire gauze with a ceramic center.  These two types of wire gauze that are made of metal have the same ability to transmit the heat efficiently, but the gauze with a ceramic center will allow the heat to be dispersed more evenly.  The ceramic at the center of the wire gauze is enmeshed at high pressure to prevent it from peeling.  There are three sizes of wire gauze with ceramic center: 4 inches, 5 inches, and 6 inches, so that different sizes of glassware can be accommodated. A Bunsen burner, named after Robert Bunsen, is a common piece of laboratory equipment that produces a single open gas flame, which is used for heating, sterilization, and combustion. Michael Faraday FRS ( ; 22 September 1791 – 25 August 1867) was an English scientist who contributed to the study of electromagnetism and electrochemistry.  His main discoveries include the principles underlying electromagnetic induction, diamagnetism and electrolysis. An ignition tube is a piece of laboratory equipment.  It is a laboratory tube used much in the same way as a boiling tube except not being as large and thick-walled.  It is primarily used to hold small quantities of substances which are undergoing direct heating by a Bunsen burner or other heat source.
