Advertisement for M. C. W. Brand Chemicals

The Mallinckrodt Company’s long-term focus on the manufacture of pharmaceutical and analytical chemicals of high purity was consistent with the training that Edward and Otto Mallinckrodt had received at Carl R. Fresenius’ Wiesbaden laboratory. This advertisement, which was published in the Bulletin of Pharmacy 14 (1900), emphasized the care and skill with which Mallinckrodt chemicals were produced and urged physicians and pharmacists to look for the M. C. W. brand.
