In the 19th century, Fruit-specialists (so called pomologists) started publishing journals and tried to promote the knowledge of the different types of apple, pears, or other kinds of stone fruit. They also manufactured lifelike fruit models made out of porcelain, papier mâché or wax. The "Fruit Cabinet of Arnoldi", for example had a variety of those models. By order of the thungarian gardening association (Thüringer Gartenbauverein) the fruit models had been manufactured and sent into the whole world. In order to improve and promote the cultivation of fruit trees, the mailings had been sent along with detailed information regarding optimal soil and location suggestions as well as information about the potential use of the plants. The first delivery had been sent in the year of 1856. Only a few of those fragile fruit models have survived time. The Landesmuseum Natur und Mensch Oldenburg has preserved one of the biggest collection of the Arnoldi Fruit in the German speaking regions.
