Reinitzer, Frederick

In 1888 Frederick Reinitzer, an Austrian botanist, discovered that the organic compound cholesteryl benzoate has an interesting and unusual property, shown in FIGURE 11.31. Solid cholesteryl benzoate melts at 145 forming a viscous milky liquid then at 179 °C the milky liquid becomes clear and remains that way at temperatures above 179 °C. When cooled, the clear liquid turns viscous and milky at 179 °C, and the milky liquid solidifies at 145 °C. Reinitzer s work represents the first systematic report of what we call a liquid crystal, the term we use today for the viscous, milky state. 

Frederick Reinitzer discovered the first compound to exhibit liquid aystal behavior in 1888. Cholesteiyl benzoate was observed to form an ordered Uquid crystalline phase when melted, and this liquid crystalline phase became an ordinary liquid at higher temperatures ...
