Peter Bayne, a Scottish author and critic, born in Aberdeenshire in 1829. He was educated at Marischal college, Aberdeen, and afterward studied theology at Edinburgh, and philosophy under Sir William Hamilton. In 1851-'2 he contributed to "Hogg's Instructor" a series of critical essays on De Quincey, Alison, Hugh Miller, and others, which attracted marked attention, and were especially commended by De Quincey and Alison. Their success determined him to devote himself to literary life, and in 1855 he published "The Christian Life, Social and Individual," in which Hugh Miller said some of the biographies "condense in comparatively brief space the thinking of ordinary volumes." This work was immediately republished in Boston, and was followed by a collection of the essays from "Hogg's Instructor," with several new ones written for this edition, under the title of "Essays in Biography and Criticism" (2 vols., Boston, 1857-'8). In 1855 he was editor-in-chief of a Glasgow newspaper, "The Commonwealth;" but in 1856 he resigned and visited Germany for health and study.

After his arrival in Berlin he was appointed to succeed Hugh Miller as editor of the Edinburgh "Witness," but did not assume that position till the summer of 1857, meantime pursuing his German studies and marrying a daughter of Gen. Gerwien of the Prussian army. He has since published in the "Witness" several extended essays and criticisms, particularly a series in defence of Hugh Miller's "Testimony of the Rocks" against an attack in the " North British Review," and these have been issued in a pamphlet edition. He has also published "Testimony of Christ and Christianity" (reprinted in Boston, 1862), and "The Days of Jezebel," a historical drama (Boston, 1872).
