Edison Lamps at the Henry Ford Museum
On this website one can find a listing of lamps in the William J. Hammer Historical Collection of Incandescent Electric Lamps (Section 12) which are housed at the Ford Museum in Dearborn, Michigan. The intent of this writing is to point out that additional information regarding lamps made at Menlo Park during the years 1879-1881 is also available in Appendix 3 of Volume 5 of The Papers of Thomas A. Edison1.

In May of 2000 the writer obtained a copy of the inventory of the Hammer lamp collection at the Henry Ford & Greenfield Village Research Center in Dearborn, Michigan. A transfer number had been assigned to each lamp in 1930. In the listing given in Section 12 of this website these transfer numbers are used. Similar numbers are used in Volume 5 of The Papers of Thomas A. Edison. However, it should be pointed out that the numbers that appear in Volume 5 are somewhat different - and yet, are the same. An example is given below where the numbers and lamp descriptions from the two sources are compared:

The Papers of Thomas A. Edison, page 1051, 1880 lamp
29.1980.529.122. Lamp made for Menlo Park street lighting, with paper horseshoe filament, large globe, supplemental tip, round inside seal, and platina vise clamps.

This website, Section 12
1880-122-----Edison. Paper horseshoe carbon filament lamp, large globe, supplemental tip, round inside seal, platina vise clamps. Made for Menlo Park street posts.
It is the number "122" that identifies these descriptions as referring to the same lamp.
