An Alb is a liturgical vestment

The alb (from the Latin Albus, meaning white), one of the liturgical vestments of the Roman Catholic, Anglican, Lutheran, and Methodist churches, is an ample white garment coming down to the ankles and is usually girdled with a cincture (a type of belt, sometimes of rope similar to the type used with monk garments). It is simply the long, white linen tunic used by the Romans.

Johannes Baptista von Albertini (17 February 1769 – 6 December 1831) was a German botanist and clergyman of the Moravian Church. He was born in the town of Neuwied.
