Harvey C. Lowrie was an American mapmaker and civil engineer active in the mid-19th century. He is best known for his cartographic work on the Midwest, particularly his 1871 Fort Wayne Guide Map. While little is documented about his early life, Lowrie’s contributions to urban cartography became significant during rapid urbanization in the United States. His work focused on creating accurate and functional maps for emerging cities, which are crucial for infrastructure planning and development. His work continues to be referenced by historians and collectors for its accuracy and attention to detail.
