Rosedale, a community northeast of the city of Baltimore, was a farming community from the time of the first settlers until suburban development began after World War II. Maryland Route 7, which runs through the community, was originally the Philadelphia Road, which carried George Washington to New York in 1789 where he was inaugurated as the first American president.
On 8 March 1909, a man named William Ramsey was lynched in the town. 
The origin of the name Rosedale is not documented with certainty. However, a 1950 fourth grade class was told to interview family and friends about the history of the Rosedale community. From that activity came an explanation.
There was a young Englishman who had a farm on Hamilton Avenue just above Philadelphia Road which was covered with beautiful roses. Since his name was Dale and since the roses were so lovely, they felt that Rosedale would be an appropriate name.
The area was settled by many German and Polish immigrants in the latter part of the nineteenth century. An article written in 1940 on the occasion of their 59th wedding anniversary tells the story of one long-time farming family in the area.
Charles Schatzschneider was born in Germany in 1859 and came to Rosedale to do farm labor at age 13. He and his wife raised 15 children and saw the area grow from a wilderness to what they saw as a highly developed community with gas and electric lighting, water and sewerage systems and paved streets. The new electric trains which whizzed past their farm were a wonder to them.
The first school, a wooden building with only two rooms, was on the corner of Hamilton Avenue and Philadelphia Road. In 1950 it was a fire house and hall.
Rosedale grew steadily as a residential suburb beginning in the 1950s. Three quarters of the housing units existing in 1990 were built between 1854 and 1979.
