The first ascent was made in 1786 by two Chamonix men, Jacques Balmat and Dr Michel Paccard, and the second in 1787 by Balmat with two local men. Later in 1787 H. B. de Saussure made the third ascent, memorable in many respects, and was followed a week later by Colonel Beaufoy, the first Englishman to gain the top. These ascents were all made from Chamonix, which is still the usual starting point, though routes have been forced up the peak from nearly every side, those on the Italian side being much steeper than that from Chamonix.
The ascent from Chamonix is now frequently made in summer (rarely in winter also), but, owing to the great height of the mountain, the view is unsatisfactory, though very extensive (Lyons is visible). In 1890 M. Vallot built an observatory and shelter hut (14,312 ft.) on the Bosses du Dromadaire (north-west ridge of the mountain), and in 1893 T. J. C. Janssen constructed an observatory just below the very summit.
