Roger Grossman, former publisher of the Marin Independent Journal and various Alameda Newspaper Group publications including the Oakland Tribune, has died at age 59 after a long battle with prostate cancer, according to an obituary this morning in the ANG Newspapers. “Roger walked the tightrope between business and journalism in a way that made it all seem more honorable,” said Charles Cooper, managing editor of the Star-Ledger in Newark, N.J., who was ANG managing editor in the mid-90s. And he preached that you couldn’t be successful as a newspaper unless you were successful as a business, Cooper said.
