 Richard August Carl Emil Erlenmeyer, also known as Emil Erlenmeyer, was a German chemist born on June 28th 1825 in Taunusstein, Germany.     At the age of 20, he started to study medicine in the University of Giessen. When he heard one of [|Justus von Liebig] <span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif">’ s lectures, he was so intrigued by the field of chemistry that he switched to study that instead. This led to his career in chemistry. <span style="FONT-SIZE: 10pt; COLOR: windowtext; FONT-FAMILY: 'Arial','sans-serif'"> <span style="FONT-SIZE: 10pt; COLOR: windowtext; FONT-FAMILY: 'Arial','sans-serif'"> <span style="FONT-FAMILY: 'Trebuchet MS', Helvetica, sans-serif"> <span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif">There was tough competition for spots in Liebig’s laboratory so he began wandering around looking for different research groups. When his money ran out, his father insisted that he become a pharmacist. <span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Arial','sans-serif'"> <span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Arial','sans-serif'"> <span style="FONT-FAMILY: 'Trebuchet MS', Helvetica, sans-serif"><span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif"> Some time after, he worked in <span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif">Robert Wilhelm Bunsen <span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif">’s laboratory on fertilisers. <span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Arial','sans-serif'"> <span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Arial','sans-serif'; mso-ansi-language: EN-CA; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-US; mso-bidi-language: AR-SA"> <span style="FONT-FAMILY: 'Trebuchet MS', Helvetica, sans-serif"><span style="COLOR: #82212f; FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif">He started to teach as a professor of chemistry, at the Munich Polytechnic School from 1868, when he was 43. He retired in 1883 due to health reasons but he still continued to be a consultant. He died at the age of 83, on January 22nd, 1909 in Aschaffenburg, Germany.

In 1861, Erlenmeyer created the Erlenmeyer flask. For more details, see below.

As well as educating at Munich Polytechnic School, Emil Erlenmeyer also formulated a principle called the Erlenmeyer Rule, in 1880. He tried to create alcohol from hydroxyls. After many failed attempts, he concluded that all alcohols changed immediately to aldehydes or ketones, as all alcohols in which the hydroxyl group is attached directly to a double-bonded carbon atom become such compounds. Erlenmeyer was one of the first people to investigate into this. The Erlenmeyer Rule is also known as [|Keto-enol tautomerism].

Emil Erlenmeyer also invented the asbestos gauze, also known as the wire gauze to Chemistry 11 students [refer to the picture in Health Chemistry: Laboratory Experiments, page ix]. This invention prevents thermal shock from glassware that have been heated by the Bunsen burner flame before the time of Pyrex® Laboratory Glassware.

Also, there is an X-File episode titled “The Erlenmeyer Flask.” <span style="FONT-FAMILY: 'Trebuchet MS', Helvetica, sans-serif"><span style="FONT-FAMILY: 'Trebuchet MS', Helvetica, sans-serif"><span style="COLOR: #000000; FONT-FAMILY: 'Trebuchet MS', Helvetica, sans-serif"> <span style="COLOR: #82212f; FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif">During the time working with Robert Bunsen in the study of fertilizers, Bunsen did not allow his associates to teach so Erlenmeyer took some of his wife’s money to mortgage a shed that he converted to a laboratory and he secretly began teaching students.

<span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif">Throughout his career, he was involved in many writing research articles and theoretical organic chemistry. <span style="COLOR: #000000; FONT-FAMILY: Verdana, Geneva, sans-serif"> <span style="FONT-FAMILY: 'Trebuchet MS', Helvetica, sans-serif"><span style="FONT-FAMILY: 'Trebuchet MS', Helvetica, sans-serif"><span style="COLOR: #82212f; FONT-FAMILY: 'Trebuchet MS', Helvetica, sans-serif"><span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif">Emil Erlenmeyer spent a lot of time <span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif">classifying ideas and concepts. He made new terms to better explain theories. He established that to organize an issue is to prepare for its resolution. [Isn’t it profound? Too bad it’s not a quote.] <span style="FONT-FAMILY: 'Trebuchet MS', Helvetica, sans-serif"><span style="FONT-FAMILY: 'Trebuchet MS', Helvetica, sans-serif"><span style="COLOR: #82212f; FONT-FAMILY: 'Trebuchet MS', Helvetica, sans-serif"> <span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif">Richard August Carl Emil Erlenmeyer had a son who is referred to as Emil Jr. His full name is Friedrich Gustav Carl Emil Erlenmeyer. Like <span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif">father and   <span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif"><span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif">son, they both have really long names and they are both chemists. Emil Jr. was born in 1864; meaning Richard Emil Erlenmeyer was 39 when he had a child! Just like other laboratory glassware, the Erlenmeyer flask can be used in the production of illegal drugs. In an attempt to restrict these productions, some areas need permission to buy laboratory glassware, including Erlenmeyer flasks. <span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif"> <span style="COLOR: #82212f; FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif"><span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif">There are also other uses for the Erlenmeyer Flask such as, a tea cup.



<span style="FONT-FAMILY: 'Trebuchet MS', Helvetica, sans-serif"> <span style="FONT-FAMILY: 'Trebuchet MS', Helvetica, sans-serif"> <span style="FONT-FAMILY: 'Trebuchet MS', Helvetica, sans-serif"><span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif">In 1861, Richard Erlenmeyer created the conical flask, which now bears his name, the Erlenmeyer flask. He created this flask because he needed something practical for all his experiments, from heating solutions to stirring its contents.

This flask is fairly similar to the beaker in the sense that they both have flat bottoms. This feature makes the Erlenmeyer flask less likely to tip over in comparison with the Florence flask and the Round-bottom flask. It is also good for heating solutions. The conical (cone-like) shape allows for its contents to be swirled or stirred during an experiment. The distinguishing aspect to the Erlenmeyer flask in comparison with the beaker is the narrow, cylindrical neck. This attribute keeps the contents from spilling and slows evaporative loss better than the beaker. As an added bonus, a rubber stopper can stopper the neck. There a markings on its side to indicate the approximate volume. Some may say the conical flask is one of the best lab equipment available.

<span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif">There are other uses for this innovative flask, like a tea cup as shown in the picture above.

The video gives some history on Erlenmeyer and the Erlenmeyer flask while explaining about acid and base neutralization. Enjoy!

<span style="FONT-FAMILY: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif"> PS. Acid and base should make salt water; the ending was just for fun. PPS. Cinda is supposed to be a graduated cylinder but I accidently forgot to draw in its supportive flat base, so it looks like a test tube. Sorry! ~ Jessica
