He worked for 22 years as gardener for the Johann Christoff Schmidt rosarium in Erfurt. His chief work, the "Rosarium", has gone through many editions. Roman Catholics use the Rosary (Latin "rosarium", meaning "rose garden") with 59 beads. The book popularized many concepts from the "Rosarium Philosophorum" in Europe. "Lilac Park", founded in 1958, has a permanent sculpture display and a large rosarium. The new rosarium is sponsored by the Club of Rose Lovers of Slovakia ("Rosa Club").
