Wilhelm HF Kuhlmann

Wilhelm HF Kuhlmann (* 1867 in Curan near Lübeck , † 1945 in Waren ) was a German entrepreneur and manufacturer of microchemical balances.

Life

Wilhelm HF Kuhlmann specialized in the construction of microchemical scales and, after having managed the workshop of the blind entrepreneur Paul Bunge in Hamburg for years , started a workshop for precision trolleys and weights for physical and analytical purposes in Steilshoperstr. 103 self-employed in Hamburg. In addition to this offer, he had automatic coin sorting machines and a mirror reading device to achieve the shortest oscillation period in the range.

Kuhlmann gained notoriety as the developer of the so-called "Kuhlmannwage", which he brought to market as "Instrument 19b" under the name "Probierwage". The later Nobel Prize winner Fritz Pregl recognized the importance of these scales for the purposes of quantitative organic microanalysis at a demonstration by Friedrich Emich around 1910 , got in touch with Kuhlmann and had Kuhlmann continuously adapt them to his needs. At that time, after the changes that had taken place, this scale was also referred to in specialist circles as the “Pregl micro-scale”. Pregl received the Nobel Prize in Chemistry in 1923 “for the microanalysis of organic substances he developed” .

Wilhelm HF Kuhlmann's company in Hamburg later fell victim to World War II.

Wilhelm HF Kuhlmann was awarded an honorary doctorate for his services in cooperation with science and was accepted as a member ( matriculation no. 3469 ) of the German Academy of Sciences Leopoldina on May 15, 1922 .
