Heinrich Geissler
Heinrich Geissler () adalah seorang ahli mesin, ahli fisika, dan peniup kaca berkebangsaan Jerman.[1] Ia dilaihirkan di kota Ingelshieb, German.[2] Ayahnya adalah seorang pengrajin kaca.[2] Ia memulai bengkel kerjanya di Bonn pada tahun , pada tahun yang sama pula, Geissler bertemu dengan rekan kerjanya, Julius Plücker, seorang ahli matematika dan fisika.[2] Bersama dengan Plucker, Geissler mengerjakan termometer dan tube kapiler.[2]
Pada tahun , Geissler dianugrahi medali emas pada pameran kelas dunia di Paris, atas kerjaninan kaca miliknya yang memiliki kualitas tinggi.[2] Pada tahun , Geissler menunjukkan penemuannya berupa pompa vakum merkuri di Universitas Bonn.[2] Pompa ini dapat digunakan untuk memompa udara keluar dari tube kaca, sehingga dapat dicapai tekanan yang sangat rendah pada tube tersebut.[2]
Geissler juga mengerjakan semacam instrumen yang dinamakan tabung Geissler.[2] Tabung tersebut berupa semacam tabung kaca bertekenan rendah, yang diisi dengan gas seperti neon atau argon, dan dihubungkan dengan anoda dan katode.[2] Lebih jauh lagi, Geissler bereksperimen dengan tabung dengan variasi ukuran, uap gas, cairan, dan tekanan udara.[ • • German physicist and glassblower (–) Johann Heinrich Wilhelm Geißler (26 May in Igelshieb – 24 January ) was a skilled glassblower and physicist, famous for his invention of the hand pumped Geissler mercury vacuum pump in the mid's and in , the Geissler tube, made of glass and used as a low pressure gas-discharge tube; these two inventions were critical technologies leading to the discovery of the electron.[2]:&#;67&#; Geissler descended from a long line of craftsmen in the Thüringer Wald and in Bohemia.[3] He found work in different German universities, eventually including the University of Bonn. There he was asked by physicist Julius Plücker to design an apparatus for evacuating a glass tube. Plücker owed his forthcoming success in the electric discharge experiments in large measure to his instrument maker, the skilled glassblower and mechanic Johann Heinrich Wilhelm Geissler. He learned the art of glassblowing in the duchy of Saxe-Meiningen He finally settled down as an instrument-maker in a workshop of his own at the University of Bonn in [3] The Geissler tube was used for entertainment throughout the s and evolved around into commercial neon lighting.
