Gruenke and his son, Bernard E. Gruenke, Jr., in the 1970s. The glass was inspired by a Czechoslovakian etched glass exhibit they saw at the World's Fair in Osaka, Japan; they called their glass "leptat," a word derived from the Czech meaning "to etch," in honor of its inspiration. The etching technique was later patented. ]]></note></mads>
