"The Reverend Timothy Alden, Jr. contributed significantly and early to higher education and the Presbyterian cause in Western Pennsylvania, as well as to antiquarian studies and the Sunday school movement. Based on Alden's unpublished letters, this biography examines the patriotism, religion, and bipolar moods that motivated Alden in the intellectual climes of New England and the rough western frontier at the beginning of the nineteenth century."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
