Ewen McIntyre (1825-1913) was a distinguished American pharmacist who spent most of his life in New York City. Born and raised in rural Pennsylvania, he came to New York at the age of 17 and became a pharmacist’s apprentice and began his studies at the New York College of Pharmacy. While still a 20-year-old student, he tested the imported British calcium carbonate in use at the shop and discovered it was in fact calcium sulfate adulterated with powdered slate. The outrage his discovery caused among American pharmacists, especially when the British supplier responded dismissively, kick-started a movement to ensure that inferior drugs could not be imported into the U.S. This led to the passage of federal legislation and the founding of the American Pharmaceutical Association to advocate for the profession. McIntyre graduated from college in 1847 and opened his pharmacy at Broadway and 18th Street three years later, in what was then the outskirts of New York City; there were no houses above 23rd Street at the time, and his pharmacy shared the intersection with businesses that raised dairy cows and pigs. In 1881 he established a branch at Sixth Avenue and 56th Street, and brought his son Ewen McIntire, Jr., into the business, renamed Ewen McIntyre & Son. In 1890 the Broadway location was closed and two years later McIntyre funded the construction of the McIntyre Building [sic], which remains on the site and was restored in 2009. Respected and valued by members of his profession, he served as the first vice president of the New York College of Pharmacy and as president from 1877 to 1890, when he became a trustee. He was also a member of the American Pharmaceutical Association and New York State Pharmaceutical Association. McIntyre was married for 60 years and fathered 15 children.
