Phil Robertson, patriarch of the reality TV show "Duck Dynasty," passed away at age 79. His family announced his death on Facebook, citing his recent Alzheimer's diagnosis. Robertson, a teacher, fisherman, and inventor of the Duck Commander call, rose to fame with the show's success. Though briefly suspended for controversial remarks, he remained a prominent figure. A private service is planned, followed by a public celebration. A new "Duck Dynasty" series will air without him.
