I. Grorce ENGELMANN. 
In the death of Dr. Engelmann, which took place on the 4th 
of February last, the American Academy has lost one of its 
very few Associate Fellows in the Botanical Section, and 
science one of its most eminent and venerable cultivators. 
He was born at Frankfort-on-the-Main, February 2, 1809, and 
had therefore just completed his seventy-fifth year. His father, 
a younger member of the family of Engelmanns who for several 
generations served as clergymen at Bacharach on the Rhine, 
was also educated for the ministry, and was a graduate of the 
University of Halle, but he devoted his life to education. © 
Marrying the daughter of George Oswald May, a somewhat 
distinguished portrait-painter, they established at Frankfort, 
and carried on for a time with much success, a school for young 
ladies, such as are common in the United States, but were then 
a novelty in Germany. 
George Engelmann was the eldest of thirteen children born 
of this marriage, nine of whom survived to manhood. Assisted 
by a scholarship founded by “the Reformed Congregation of 
Frankfort,” he went to the University of Heidelberg in the year 
1827, where he had as fellow students and companions Karl 
Schimper and Alexander Braun. With the latter he main- 
tained an intimate friendship and correspondence, interrupted 
only by the death of Braun in 1877. The former, who mani- 
fested unusual genius as a philosophical naturalist, after layin 
the foundations of phyllotaxy, to be built upon by Braun wad 
others, abandoned, through some singular infirmity of temper, 
an opening scientific career of the highest promise, upon which 
the three young friends, Agassiz, Braun and Schimper, and in 
his turn Engelmann, had zealously entered. 
Embarrassed by some troubles growing out of a political 
demonstration by the students at Heidelberg, Engelmann in 
the autumn of 1828 went to Berlin University for two years; 
and thence to Wiirzburg, where he took his degree of Doctor
