Might a kind colleague be able and willing to share a copy in any form of Meta Benfey's biography of her father, Theodor Benfey, apparently privately printed in 1909? I am particularly interested in his early years in Frankfurt (1830–1832) and Heidelberg (1832–1834). According to Windisch's Geschichte der Sanskrit-Philologie, the relevant section would include pages 19–20.

With thanks and best wishes,
