One of the earliest known polarizer types was the calcite Nicol prism, invented in 1828.  This polariscope originally contained two Nicol prisms, one for generating an incident polarization onto a sample and a second for analyzing the state of polarization transmitted by the sample.  This type of polariscope was invented in the mid 1800ís and was common well into the 20th century for analyzing crystal structure and other applications.
