The
above photograph was taken at the first Board of Trade to stand at the foot of
La Salle Street and shows scores of traders in action. It was taken on this date, April 4, 1903.
The
largest amount of flash powder ever used was employed in the completion of the
photograph. George R. Lawrence, the
photographer, used a dozen pounds of the power in capturing the members of the
board of trade working in the pits.
According
to The Chicago Tribune the powder was
distributed in 360 lights that hung from the balcony rails, “discharged
simultaneously by electricity.”
Mr.
Lawrence was busy that week. He had
earlier taken a photograph of 65 celebrants at a banquet held in honor of
President Theodore Roosevelt at the Auditorium Annex. Later in the week he stood atop a one hundred
foot tower in the Chicago stockyards to take a picture of the action on the
southwest side of the city.
