The first major producer of items made of uranium glass is commonly recognized as Austrian Franz Xaver Riedel, who named the yellow (German: Gelb) and yellow-green (German: Gelb-Grün) varieties of the glass "annagelb" and "annagrün", respectively, in honor of his daughter Anna Maria. Riedel was a prolific blower of uranium glass in Unter-Polaun (today Dolni Polubny), Bohemia from 1830 to 1848.
