[7] The 1937 All-Star Game was one in which pitcher Dizzy Dean sustained a toe injury that negatively affected the rest of his career.
The following year, on June 15, 1938, Barr worked as the First Base Umpire for an unprecedented event in baseball history, as the Reds' Johnny Vander Meer threw a second consecutive no-hitter at Ebbets Field.
[3] Barr was the home plate umpire on September 28, 1938, when the Cubs' Gabby Hartnett hit the famous "Homer in the Gloamin" at Wrigley Field.
Being mobbed by players and fans in circling the bases, Hartntett recalled Barr making sure he touched home plate.
[13] On September 18, 1946, at the Polo Grounds Barr collapsed from a heart attack during a New York-Chicago game, but he recovered to resume umpiring again.
[16] After umpiring in the 1948 World Series, Barr was briefly confined at home under a physician's care for an undisclosed illness.
[17] Barr was the first-base umpire in a three-man crew during the second game of an August 21, 1949, doubleheader between the Phillies and Giants at Philadelphia's Shibe Park.
In the top of the ninth inning, Barr ruled that Phillies' center fielder Richie Ashburn had trapped rather than caught a fly ball hit by New York's Joe Lafata.
Fans reacted by repeatedly throwing fruit and bottles at the umpires causing them to abandon the field for their safety.
Future major league umpires Bill McKinley, Scotty Robb, Bob Engel, Ken Burkhart and Dick Stello were students at Barr's school.
[26] He instituted a system of 10 cent fines, paid to the hotel's waitresses, for student mistakes or silly questions.
[28] Barr also took his instruction out of the United States, holding Umpiring clinics in Canada, Germany, Puerto Rico, Korea and Japan.
He operated his umpire school until 1967 while serving as president of the Western Association (1953-54) and the Sooner State League (1956-57).
[35] Barr previously had written a section on Umpiring in The Sporting News 1951 soft cover book: How to Play Baseball.
