I couldn't find specific information directly linking Emmy Lischke's work to a significant event in Chicago in 1893 with the searches performed. However, one major event in Chicago in 1893 was the World's Columbian Exposition, also known as the Chicago World's Fair. This exposition attracted artists from around the world and showcased numerous works of fine art.

If you are researching Emmy Lischke's participation in historic events, it might be likely that her work was presented at this event, given the significance and wide participation in the World's Columbian Exposition.

For more precise details, you might consider looking into records of the art exhibitions held at the exposition or specific mentions of her name in historical journals or archives dedicated to the fair.
