Beth Murphy, owner of Murphy’s Bleachers, a popular bar among Chicago Cubs fans, was as well-known in Wrigleyville as some of the players. Murphy’s battles with the Cubs over rooftop owners’ rights played out in newspapers and on local newscasts for years, pitting the small business owners against one of baseball’s oldest and most valuable franchises. It made Murphy a local celebrity and one of Wrigleyville’s most respected business owners. “She always valued the bar’s contribution to the neighborhood,” said Karen Cholipski, her longtime friend. Murphy, 68, died Monday after a long bout with kidney cancer. The bar announced her death on Twitter, saying she “peacefully passed away” in the morning.
