Description

Clocks are well suited to be combined with globes because world time is based on the full rotation of the earth once every 24 hours. A number of Continental, English, and American globes were made incorporating a clock mechanism, to not only show relative time around the world, but to keep time for the user of the globe. The time of day or night on the earth varies with longitude location. There are 24 time zones in the world. Generally globes are divided into 24 longitudinal lines, each 15 degrees apart. It takes the earth one hour to turn each 15 degrees, and in 24 hours it has completely turned once.

To use the clock globe set the local time on the dial. Turn the globe so that the place of use corresponds to the correct time on the equatorial hour circle. Local time for any place in the world then can calculated.

The clock movement works. Globe generally good and clean. See generally, Article in NAWCC Bulletin (June 1999, p. 423) showing a related example.

Ludwig Julius Heymann was a prolific German globe maker based in Berlin. He began as a bookseller in Breslau in 1858 and moved the shop to Berlin in 1861. In 1883, he began producing globes under the company name Geographisch-artistische Anstalt [Geographic Artistic Institute] Ludwig Julius Heymann. Professor Henry Lange (1821-1893) was a longtime Heymann employee and designer of the gores. Heymann produced a wide range of terrestrial globes, from 5 cm to 36 cm in diameter, some of which were for export and thus in languages other than German. The stand styles ranged from simple wooden ones to elaborate decorative metal stands with sculptural figures supporting the globes. After Heymann’s death in 1899, the company was run by a succession of owners and moved to Leipzig around 1909. After World War I it issued some globes with Wagner and Debes. The company went out of business in 1930.
