Helmut N. Friedlaender, a book-loving lawyer and financial adviser whose quietly assembled collection of early printed books and illuminated manuscripts caused a stir in bibliophilic circles when it went to auction, died on Tuesday in Yarmouth, Me. He was 95 and lived in Manhattan.

The books and manuscripts sold included one of the first classical texts ever printed, Cicero’s “De Officiis” (“On Duties”). Published on vellum in Mainz, Germany, in 1465 by Gutenberg’s successors, it fetched $666,000. A 14th-century illuminated manuscript of St. Gregory’s “Moralia in Job” (“Commentaries on the Book of Job”), in its original doeskin binding, from Bohemia, went for $248,000.
