A portrait of Johann Sebastian Bach that was one of only two known to have been painted in Leipzig during his lifetime will return after more than 265 years to the German city where he worked and is buried.

E.G. Haussmann's 1748 portrait of a bewigged and probing-looking Bach in his 60s, holding a sheet of music in his right hand, is valued at $2.5 million.

It has been donated to the Leipzig Bach Archive by the estate of its most recent owner, the late William Scheide of Princeton, N.J., a philanthropist and avid Bach enthusiast.
