ALS signed “N. Tesla,” one page both sides, 4 x 2.5, no date but circa 1892-1895. Handwritten letter to a gentleman, in full: "I have an engagement this morning and regret my inability to meet you this morning. I am here every evening at about 9 o'clock during the day at my laboratory 35 South Fifth Ave. You may meet me there from 11-12 AM or here in the evening." In fine condition, with clipped corners, and a small rusty paperclip impression to the top edge.
In August 1892, Tesla moved his lab to 33-35 South Fifth Avenue where he took up the fourth floor; he remained there for two-and-a-half years before the building burnt down. The New York Times quoted Tesla when reporting on the fire: 'I am in too much grief to talk. What can I say? The work of half my lifetime, very nearly all my mechanical instruments and scientific apparatus, that it has taken years to perfect, swept away in a fire that lasted only an hour or two. How can I estimate the loss in mere dollars and cents? Everything is gone. I must begin over again.'
