Robert Bunsen: Google Doodle celebrates Chemist’s 200th birthday
Google Doodle celebrates the 200th birthday of popular chemist Robert Bunsen.Google celebrates German Chemist’s 200th birthday, chemicals in bottles on today’s Google Doodle.Google Doodle is back with another technology-related celebration. And this time, the search engine giant is celebrating the 200th birthday of German chemist Bunsen, Robert Wilhelm von, or Robert Bunsen in short.Familiar right? Bunsen might be familiar, especially if you already finished your Chemistry subject, because he invented the Bunsen burner — an apparatus inside our Chemistry laboratories.Bunsen Burner is the thing to use if we need to produce a gas flame for heating our chemicals, as well as sterilization, and combustion. Apparently, Google Doodle’s...
Posted in: Events200th Birthday of Robert Wilhelm Bunsen
Robert Wilhelm Bunsen did groundbreaking work in organic chemistry and spectrometry, but he's more famous for the laboratory gas burner that bears his name.Born on March 30, 1811 in Göttingen, Germany, Bunsen studied chemistry in Göttigen, and obtaining his Ph.D. degree in 1831. In 1833 he became a lecturer at Göttingen and three years later accepted an associate professorship at the University of Marburg. He was promoted to full professorship in 1841. In late 1852 Bunsen became the successor of Leopold Gmelin at the University of Heidelberg, Germany, where he remained until his retirement in 1889.Bunsen investigated emission spectra of heated elements, and with Gustav Kirchhoff discovered caesium (in 1860) and rubidium (in 1861)....
Posted in: EventsRobert Bunsen Biography
When confronted by the vast array of apparatus used in chemistry lab, a student can usually identify with a high degree of confidence one of the more familiar pieces of equipment, the Bunsen burner. While this essential piece of laboratory equipment has immortalized the name of Robert Wilhelm Bunsen, it was not invented by him. Bunsen improved the burner's design to aid his endeavors in spectroscopy. Ironically, Bunsen will be remembered by generations of chemistry students for a mere improvement in a burner design, when his other contributions to the field of chemistry are vastly more significant and diverse, covering such areas as organic chemistry, arsenic compounds, gas measurements and analysis, the galvanic battery, elemental spectroscopy...

This edited article about Robert Wilhelm Eberhard Bunsen originally appeared in Look and Learn issue number 917 published on 18 August 1979.When a new laboratory was built at Heidelberg, in Germany, in 1855, a chemist was asked to look at the various devices proposed for the supply of heat for chemical experiments. A blowlamp was generally used for these, but the scientist wanted something more convenient to handle.Robert Bunsen’s gas burner (F) became part of everyday chemical apparatusFinding nothing to suit him, he soon devised a simple means of burning ordinary coal gas with a hot, smokeless flame. His burner was such a good and easy means of obtaining an intense heat that within a short time it became widely used...

Bunsen Burner DimensionsThe Bunsen burner is a type of laboratory equipment utilized for combustion and sterilization. It does this by generating a solitary gas flame. It is named after its inventor, Robert Bunsen. Bunsen Burner Dimensions There are slight variations in the size depending on how the equipment was designed. For example, there are Bunsen burners that measure 4.1" W x 1.9" H x 5.1" D (103 x 49 x 130 mm).Others measure 5.1" W x 2.9" H x 6.1" D, and still others 4.5" W x 2.5" H x 5.5" D. The burner shaft cover also varies, with some coming at 23 mm and others at 25 mm, 28 mm and other sizes. The burner usually weighs anywhere from a pound to two pounds. Features and Usage While the Bunsen burner dimensions...
Posted in: ScienceRobert Wilhelm Bunsen (1811-1899)
Bunsen was born on March 31, 1811 in Göttingen, Germany, the youngest of four sons. As his father was a professor of modern languages at the university, an academic environment would surround him from birth. After schooling in the city of Holzminden, Bunsen studied chemistry at Göttingen. Receiving his doctorate at age 19, Bunsen set off on extensive travels, partially underwritten by the government, that took him through Germany and Paris and eventually to Vienna from 1830 to 1833. During this time, Bunsen visited Henschel's machinery manufacturing plant and saw the "new small steam engine." In Berlin, he saw the mineralogical collections of Weiss and had contact with Runge, the discoverer of aniline. Continuing on his journeys, Bunsen met...

The 31st of March 2011 marks the 200th anniversary of the birth of Robert Bunsen (1811-1899). Bunsen was a German chemist perhaps most famous for his invention of the Bunsen Burner; this was actually the latest in a series of improvements to the laboratory burners already in use but proved to be the most effective and came to make his name familiar to every young student of the chemical sciences.Robert Bunsen was one of the most influential chemistry teachers of his time, teaching at the Universities in Marburg, Breslau & Heidelberg as well as the Polytechnic School of Kassel. Some of his more notable students included Henry Roscoe, Friedrich Beilstein, John Tyndall, Edward Frankland and Dmitri Mendeleev (creator of the Periodic...
