Geisslern.

Brit.

/ˈɡʌɪslə/, U.S.

/ˈɡaɪslər/

Etymology: < the name of Heinrich Geissler (1814–79), German mechanic and glass-blower.

Used attributively (†or in the possessive) to designate certain apparatus invented by Geissler, as Geissler tube n. a sealed glass tube containing gas at low pressure and a pair of electrodes so designed that a luminous discharge can be produced between them.
