on the first floor and the windows looked out onto the courtyard surrounded by
the five experimental buildings--this was the ideal place for the supervision his
experimenters’ work. For example, shop order number 2140 was for taking down the partitions
in room ô. 647-48. Number 2140 comes from Notebook N-09-01-21 and dates from around 1909. Room was established Edison’s personal
experimental room.
Dyer and Martin locate both John and Fred Ott the second floor. The
two rooms situated between Edison’s room and the precision machine shop
might have been the glass blowing and vacuum pump rooms. images plans these two rooms have been found.

divisions between rooms were made thin wood panelling which could be
removed without too much effort.
Multiple doors opening into the hallway and scars the ceiling planks suggest
that the large room the south side the second floor was once several smaller
rooms numbered and The row rooms the south side the precision
machine shop could also have been altered, for there evidence the ceiling of
several partitions. Although the
experimental rooms were primarily spaces customized for the job hand,
Edison’s plans for the laboratory show that some functions, such glass blowing
and vacuum pumping, were permanently assigned experimental rooms.44 was Edison’s practice change the rooms around he
embarked new projects, although very little known the specific changes." Fred Ott placed "in one the many experimental-rooms lining
