Johan Gustaf Ruckman
Johan Gustaf Ruckman (December 12, 1780 – January 20, 1862) was a Swedish engraver.

Biography
Ruckman was born in Stockholm in 1780.

In 1805, being a pupil of Johan Wilhelm Palmstruch, Ruckman helped with the preparation of tables in Palmstruch's work Svensk botanik ("Swedish Botany"). From the fifth volume of this series, he designed several pages independently. At the same time he helped Palmstruch and Conrad Quensel with the preparation of Svensk zoologi ("Swedish Zoology"). From the seventh volume of Svensk Botanik (1812) until the completion of the eleventh volume (1838), Ruckman personally engraved all the printing plates. Ruckman found time to further develop his artistry and designed a number of portraits. He also illustrated fashion journals, calendars, and children's books; writings of the Swedish Academy of Sciences and other scientific institutions; and about 100 map sheets. Ruckman is well represented in the collection of engravings of the Swedish National Museum.
