) in 1854, was appointed as a temporary university assistant (amanuensis'') at the
Royal Library in
Stockholm, but returned to
Lund where he was awarded Master of Philosophy in 1856. During this and the following years he served at the schools in
Helsingborg and Stockholm, and for a few months as acting consistory notary ('''') during the
bishop's visitation in the
Diocese of Lund and as acting secretary to the chancellor of Lund University. During a six-month stay in Paris (1856–1857), he devoted himself to archival research and to the French press in a
Scandinavianist direction. After resuming service at the Royal Library, he was appointed second amanuensis in 1858, second amanuensis in 1861 and first amanuensis the same year, and
librarian there from 1877 to 1900. For 13 years (1857–1870) he was also librarian to

His ('Pictures and Memories') (1889) includes a parliamentary gallery (from
Stockholms Dagblad) and obituaries (from and the calendar ''
). writes in Nordisk familjebok'': "In the art of biographies, W. must have been the foremost among the Swedes of his time. His perceptiveness in the fields of politics, learning and publicity, combined with a sympathetic outlook and a clear, smooth, and varied manner of presentation, made him particularly suited to the work of a biographer." More comprehensive biographical works by him are
Lars Johan Hierta (1881), "which in richness of fact and presentation is among our best monographs" (), and (1884) about
Camillo di Cavour. Also worthy of mention are the portraits (1897) and the biographies of artists
Johan Fredrik Höckert (1900) and
Johan August Malmström (1904). Wieselgren also wrote articles for
