Raffaele DeAngelis was the oldest pharmacist who owned and operated one of the first apothecaries in Rhode Island which was limited to compounding prescriptions. Of Italian heritage, he was known as "Don" Raffaele, which is a title of respect given to Italian men of great importance. Known for his accomplishments in the drug and chemical fields, he was also widely respected for his leadership in serving his fellow man.

Mr. DeAngelis founded the Chemical Industrial Co., Providence, RI. He held many patents in the field of medicine and it is said he compounded one of the first citrates for antacids in the patent medicine industry. Besides his citrate he manufactured and sold other products such as FERRO-CHINA DeANGELIS, a tonic, DeANGELIS' LINIMENT, DeANGELIS' LIQUID DENTRIFICE, CICO DIGESTIVE POWDER, and DeANGELIS' MAGNESIUM CITRATE.

The bottles containing these products were cylinder shape in cobalt blue color and came in several different sizes. A couple of different clear embossed 'medicine' type bottles have been reported although the cobalt ones are the most popular. The earliest DeAngelis bottles are blown in mold form. The earliest machine made bottles are similar in appearance to the blown in mold variants, but the seam extends through the lip. The later bottles are the screw cap variety and are readily available.

Mr. DeAngelis passed away in July, 1970 at the age of 94.
