He died in office in 1903, possibly due to chromate poisoning from his years handling chromium to perfect his chrome tanning technique.

Foerderer invented a chrome tanning technique for treating animal skin with chromium sulfate that resulted in a soft and supple leather for the production of handbags, shoes and gloves.

[5] Foerderer also partnered with the Rohm & Haas chemical company to implement the use of Oropon as a replacement for dog dung in the leather softening process.

[6] Foerderer's company began as a one-room factory in the Frankford section of Philadelphia and eventually grew to cover 17 acres.

[12] It is possible that he died from chromate poisoning from his years handling chromium for his chrome tanning technique although the cause of death was listed as Bright's disease.

[11] Foerderer's son, Percival took over management of the leather goods business and is known for building the La Ronda mansion and estate in Bryn Mawr, Pennsylvania.
