American architect
John Bailey McElfatrick (1828–1906) was an architect known for his design of theaters in the United States and Canada. He eventually went into practice with his sons William H. McElfatrick and John Morgan McElfatrick (1853-1891) in the firm J. B. McElfatrick &amp; Sons.
McElfatrick established a practice in 1851 in Harrisburg and Philadelphia after studying architecture and engineering with his father Edward McElfatrick. The firm expanded to St Louis, Cleveland, and Chicago and also designed theaters in Ottawa and Montreal. He is credited with the design of more than 100 theaters and for instituting improved sight lines, multiple exits, fire sprinkler systems, and continuous rows of seating without aisles on the ground floor.
His work includes the Central Colored School at 542 West Kentucky Street in Louisville, Kentucky. It is listed on the National Register of Historic Places.
Several theaters that he designed remain in use.
