What was the name of the legendary announcer for the Chicago Cubs?

Most people today would say Harry Carey, but before Harry there was Jack Brickhouse. Also, a legendary broadcaster whose signature call "Hey Hey" appears on the left field foul pole. The Cubs wore a patch with that phrase on it after he passed away in 1998. The same year Harry passed away. Some fans today might even say the Ron Santo is a legendary broadcaster for the Cubs. Granted his legacy is his play on the field and not in the booth, (although his call when Brant Brown dropped an easy fly ball in September 1998 is legendary) but he is definitely a Cubs legend like no other, except maybe Ernie Banks.
