Charles Henry Phillips (1822 – 1888) was an English pharmacist who is universally known for his invention Phillips' Milk of Magnesia.[1][2]

Early days[edit]

He moved from England to an estate at 666 Glenbrook Rd. in Glenbrook, a section of Stamford, Connecticut and established the Phillips Camphor and Wax Company in that community.

The antacid concept[edit]

It was in Stamford that he concocted and received a patent in 1873[3] for hydrate of magnesia mixed with water which he called Milk of Magnesia.

Final days, achievements and legacy[edit]

Phillips produced milk of magnesia as well as other pharmaceuticals at his Glenbrook firm, which incorporated in 1885 as the Charles H. Phillips Company. After Phillips' sudden death of apoplexy in New York on 29 October 1888,[4] his four sons ran the corporation until 1923, at which time it was acquired by Sterling Drug, Inc. Phillips' Milk of Magnesia is still manufactured today, but the last familiar blue bottle to be filled in Stamford was in 1976, when production at the Glenbrook plant was phased out. Sterling, and its Phillips' Milk of Magnesia, was purchased by Bayer in 1994.
