About this collection

This digital collection contains the complete manuscripts of Wisconsin scientist Increase A. Lapham (1811-1875) owned by the Wisconsin Historical Society.  Containing about 40,000 pages in 294 folders, the online resource includes Lapham’s correspondence, diaries, scientific notes, and other papers.

A detailed inventory of the physical papers can be seen at the link below. 

Because nearly all 40,000 pages are handwritten, searching the text of each page is impossible. Each folder was therefore carefully described.  Online searches will retrieve entire folders likely to contain the information requested.  Click a thumbnail to open a folder and then browse its table of contents in the right-hand frame to locate relevant pages.

Development of this digital resource was supported by generous funding from the Council of University of Wisconsin Libraries/University of Wisconsin System, in addition to the Hollister Fund at the Wisconsin Historical Society.  

Rights: All documents in the Lapham Papers are free from copyright restrictions. We encourage you to use them however you wish, but ask that you always cite them clearly and include a link back to this page. High-resolution files can be provided for a fee; see our FAQs About Buying Historical Images for more information.
