Lucas Haasis found a time capsule: A complete mercantile letter archive of the merchant Nicolaus Gottlieb Luetkens who lived in 18th century Hamburg. Luetkens travelled France between 1743-1745 in order to become a successful wholesale merchant. He succeeded in this undertaking via both shrewd business practice and proficient skills in the practice of letter writing.
Based on this unique discovery, in this microhistorical study Lucas Haasis examines the crucial steps and activities of a mercantile establishment phase, the typical letter practices of Early Modern merchants, and the practical principles of persuasion leading to success in the 18th century.
