M.M.White undertaker WashingtonDC Matthias M. White undertaker of Washington , DC Fisk and Raymond metallic coffins

Daniel Webster was one of the famous people to endorse Fisk coffins and he was buried in one in Massachusetts in 1852. My guess would be Mister Fisk sent one to Boston and that a local undertaker handled the funeral. This article describes (in detail) how the body looked after being in a sealed metal coffin.

The Fisk company had burned in 1850 and RD Fisk died in 1852 so its unclear how the Fisk casket was obtained in Boston.

Gleason's Pictorial magazine of November 13 and 20, 1852 featuring images of Daniel Webster's Funeral  "THE REMAINS OF MR. WEBSTER IN HIS LIBRARY, AT MARSHFIELD, MASS." and  "THE METALLIC CASE" (You can see the metallic coffin on the caisson )

An unearthed Fisk casket in DC contained a mummy of a young boy that was for a time, believed to possibly be William White, son of my great, great grandfather M.M. White. I worked with the
Smithsonian team to help trace the genealogy of the boy. Because M.M. White was the sole proprietor of Fisk caskets in DC from 1849-1867 and had a son named William that also died during that time he was a candidate for the found body It turned out to be another William White but was very interesting project. The mystery was solved through DNA and his rightful family was found. My brother and I (by special invitation) visited with the anthropologists and the William White mummy at the Smithsonian Museum DC in 2006. Featured the wonderful Deb Hull-Walski.

 There are many famous "mummy" stories connected to the use of Fisk's caskets. ( Fisk & Raymond iron coffins )

White was also famously buried First Lady, Dolly Madison and Vice President John C Calhoun in Fisk caskets.

  On the afternoon of Oct. 4, 2011, a backhoe dug into an excavation pit in Elmhurst, Queens, and struck iron. Construction workers assumed they had hit a pipe. But when the claws of the backhoe emerged from the ground, it was dragging a body clothed in a white gown and knee-high socks.  

Martha Peterson “She would have been 26 in 1850, probably died around 1851 and lived in the household of William Raymond, a partner in the iron-coffin maker Fisk & Raymond"
