Analysis of information sources in references of the Wikipedia article "Conrad Black" in English language version.
in 1981, Canadian financier Conrad Black of Norcen Energy Resources, Ltd., initiated a year-long takeover battle. Black's purchase of a large block of Hanna stock in October 1981 quickly captured the attention of Hanna chairman Robert F. Anderson and other members of the board. After a relatively brief, but heated federal hearing, Black and Hanna made a standstill agreement that gave Black 20 percent of Hanna in exchange for $90 million. Black became a director, and the last descendant of an M. A. Hanna & Company partner, George M. Humphrey II, resigned from his position as senior vice president by 1984.
