As Arlington celebrates its sesquicentennial throughout 2026, we are sharing stories about the people, places and moments that made The American Dream City what it is today.

This month, we are celebrating another pioneer in Arlington's rich history: Officer Fletcher Ray, the city’s first full-time Black police officer. Officer Ray joined the force in 1969, when Arlington was a close-knit community of about 89,000 residents and the police department had fewer than 100 officers. He served the Arlington community until 1971.
