Swedish-American Army engineer (1803-1889) who designed and built the ironclad warship Monitor for the American Navy. ALS signed “J. Ericsson,” one page both sides, 7.75 x 10, October 18, 1858. Letter to gentleman, in part: "I went to Strang's on Saturday and in less than 1 1/2 hour had the heater out…By 8 o'clock the new heater was at Strang's door, but through misunderstanding and superlative stupidity the door was closed…I can find no words to express my annoyance…Tyler has been with me…as you may know, and wants to build engines suitable for thrashing &c as in that line the demand is beyond intimate—the application of the vacuum cylinder for the back stroke Tyler thinks…will make the patent valuable." Ericsson concludes with a postscript, initialed "J. E.," plus an additional passage penned on a clipped slip which was once affixed to the second integral page. In fine condition, with old adhesive residue and mounting remnants along the hinge.
