Carl Olof Rosenius

Carl Olof Rosenius (3 February 1816 – 24 February 1868) was a Swedish lay preacher, author and editor of the monthly ''Pietisten'' (The Pietist) from 1842 to 1868. He was one of the country's most widely-heard preachers of his day and has been described as being of "extraordinary importance for the low-church evangelical revival not only in Sweden but also in the other Nordic countries".
