Today in Delaware County history, June 4

100 Years Ago, 1924: Following mad dog scares in different parts of the county, Mayor Turner has communicated with the Bureau of Animal Industry, State Department of Agriculture, making inquiry as to just what the laws are concerning dogs running at large. He has received the information that the payment of a state license for a dog is no more than registration of ownership and carries with it little or no privileges permitting dogs on streets or highways unless they are in personal charge of their owners.

75 Years Ago, 1949: The Ford Motor Co. plant in Chester will reopen at midnight Tuesday after being idled for more than four weeks by a strike at the company’s huge River Rouge plant. William D. Singleton, plant manager, announced that the 1,485 workers who were laid off would be completely recalled with full crews beginning work at midnight Tuesday.

50 Years Ago, 1974: When members of Chester High School’s Class of 1974 receive their diplomas at 6:30 tonight at Sun Chester in Chester Township, they will at once become members of an exclusive fraternity which took root in this community a century ago. The 595 graduating seniors will be the 100th and ironically the last class to graduate from Chester High School as it is now known. In September, the Greystone building at Ninth and Fulton streets will surrender all but its memories to a new $22-million seat of secondary education currently under construction two blocks away at Ninth and Barclay streets.

25 Years Ago, 1999: A soft drink company has approached the Aldan Recreation Board with a proposal to provide a scoreboard for Schwenke Field, free of cost, in exchange for the borough’s agreeing to sell only the company’s product in the ballfield snack bar. The scoreboard would contain the company’s logo. Council President Joseph McCollian said he’s not in favor of the idea. “I like ‘free,’ but I don’t like commercializing the field with a sign with advertising,” he said.

10 Years Ago, 2014: A prep school graduate who allegedly led the so-called Main Line Take Over Project has pleaded not guilty to charges he peddled marijuana and cocaine via the drug ring to college and high school students. The 25-year-old, who remains in Montgomery County jail in lieu of $1 million bail, previously worked at a medical marijuana dispensary while living in California. He was one of 11 people arrested in April when the alleged drug operation was dismantled by county detectives.
