The first Walgreens drugstore, which opened in 1901 was founded by Charles R. Walgreen. The quality of Walgreen's pharmaceutical compounds (he became a registered pharmacist in 1897) met the very highest standards for purity and freshness. Many of the products that have enriched our lives over the decades were developed and manufactured by Walgreens. Walgreens, has been a welcome, dependable presence in countless neighborhoods across the country for more than 100 years.
