This distinguished traveller was born on the 16th of September, 1651, at Lemgow, a small town in the territories of the Count de Lippe, in the circle of Westphalia. His father, who was a clergyman, bestowed upon his son a liberal education suitable to the medical profession, for which he was designed. It is probable, however, that the numerous removals from one city to another which took place in the course of his education,—his studies, which commenced at Hameln, in the duchy of Brunswick, having been successively pursued at Lunebourg, Hamburgh, Lubeck, Dantzick, Thorn, Cracow, and Kœnigsberg,—communicated to his character a portion of that restless activity and passion for vicissitude which marked his riper years. But these changes of scene by no means impaired his ardour for study. Indeed, the idea of one day opening himself a path to fame as a traveller appears, on the contrary, to have imparted additional keenness to his thirst for knowledge; his comprehensive and sagacious mind very early discovering in how many ways a knowledge of antiquity, of literature, and the sciences might further the project he had formed of enlarging the boundaries of human experience. Having during his stay at Kœnigsberg acquired a competent knowledge of natural history and the theory of medicine, he returned at the age of thirty to his own country; whence, after a brief visit, he again departed for Prussia and Sweden. Wherever he went, the number and variety of his acquirements, the urbanity of his manners, and the romance and enthusiasm of his character rendered him a welcome guest, and procured him the favour of warm and powerful friends. During his residence in this country, at the university of Upsal and at Stockholm, he became known to Rudbeck and Puffendorf, the father of the historian; and it was through the interest of the latter that, rejecting the many advantageous offers which were made for the purpose of tempting him to remain in Sweden, he obtained the office of secretary to the embassy then about to be sent into Persia. The object of this mission was partly commercial, partly political; and as the Czar of Russia was indirectly concerned in its contemplated arrangements, it was judged necessary that the ambassador should proceed to Ispahan by the way of Moscow.
