McClatchy attended Santa Clara University, where he earned a Masters of Arts in 1901.
[1] He took over the Sacramento paper upon the death of his father, James McClatchy, in 1883 and led it into the 20th century, continuing the newspaper's battles for labor rights; against the abuses of big mining, the railroads, and corrupt government; and fiercely defending a publication's right to editorial freedom.
[2] McClatchy also owned KFBK (AM), an AM radio station in Sacramento.
His son, Carlos, who had been groomed to take over the business, died in 1933; McClatchy then turned to his daughter, Eleanor, who after his death became president of the McClatchy Company and led it for the next forty years.
McClatchy High School in Sacramento, which opened in 1937 about a year after his death, was named in honor of McClatchy.
