outlining “the present state of<br />

the science and art of illumination,”<br />

the scope of the new <strong>Society</strong>,<br />

its aims and objects, and<br />

the relation of the new society<br />

to other organizations. Marks<br />

summary of the present state of<br />

lighting focused on two issues:<br />

the problem of discomfort glare<br />

and providing better value for<br />

the consumer’s dollar. On discomfort<br />

glare he noted that:<br />

“Though much attention<br />

has recently been given to<br />

the subject of globes, shades<br />

and reflectors, the fact still remains<br />

that unshaded or inadequately<br />

shaded lamps are the<br />

rule rather than the exception.<br />

In considering the present status<br />

of the science and art of<br />

illumination there is perhaps<br />

no question that is in need of<br />

more immediate attention<br />

than this one. The practice<br />

of placing lights of excessive<br />

intrinsic brightness within<br />

the ordinary field of vision is<br />

so common as to cause great<br />

apprehension among those<br />

who have studied the question<br />

from a physiological point of<br />

view that our eyesight is suffering<br />

permanent injury.”<br />

Marks had done research with<br />

current U.S. Census Reports,<br />

Union Carbide (Acetylene) and<br />

Standard Oil, and listed the following<br />

consumer costs of lighting<br />

for 1905:<br />

•<br />

•<br />

Electric light $120 million<br />

Coal and water gas $40 million<br />

•<br />

•<br />

•<br />

Natural gas $1.7 million<br />

Acetylene $2.5 million<br />

Oil $60 million<br />

The total, about $220 million,<br />

was probably an underestimate.<br />

About the scope of the society,<br />

Marks noted that:<br />

“The term ‘engineering,’ as<br />

used in the name of this <strong>Society</strong>,<br />

unless viewed in its broad<br />

sense, is to a certain extent a<br />

misnomer, as the <strong>Society</strong> will<br />

deal with some phases of illumination<br />

that may not properly<br />

be said to come within the<br />

distinct field of engineering,<br />

such for instance as the physiological<br />

side of the question.<br />

The <strong>Society</strong> will be interested<br />

in every phase of the subject<br />

of illumination whether from<br />

an engineering point of view<br />

or otherwise, and will throw<br />

its doors quite as wide open to<br />

the layman as to the professional.<br />

It will not, however,<br />

deal with questions relating<br />

to the production or distribution<br />

of the energy from which<br />

the light produced.”<br />

The discussion of Marks presidential<br />

address was long and<br />

detailed. Those present included<br />

representatives from all sectors<br />

of the lighting industry: electric<br />

and gas suppliers, equipment<br />

manufacturers, consultants and<br />

academics. Enthusiasm arose<br />

from every corner. The meeting<br />

and its participants drew the<br />

attention of the press. The following<br />

morning an editorial ap-<br />

peared in the New York Tribune<br />

entitled The Art of Lighting.<br />

On January 28, 1907, the headquarters<br />

was moved from the<br />

temporary space that had been<br />

provided by the Holophane Glass<br />

Company, to an office in the <strong>Engineering</strong><br />

Societies’ Building,<br />

at 29 West 39th Street. The first<br />

annual meeting was held on<br />

January 7, 1907. By then the organization<br />

had established itself<br />

nationally, with sections in New<br />

England, Chicago, Pittsburgh,<br />

Philadelphia and New York.<br />

Membership stood at 815 at the<br />

time of that first anniversary<br />

meeting and the first year’s budget<br />

had been $4000.<br />

The <strong>Society</strong> began publishing<br />

immediately. Volume 1, Number<br />

1 of the Transactions of the <strong>Illuminating</strong><br />

<strong>Engineering</strong> <strong>Society</strong><br />

appeared in February 1906. In<br />

the 11 months of its first publication<br />

year, the <strong>Society</strong> printed<br />

more than 400 pages of technical<br />

presentations and discussions<br />

dealing with all aspects of<br />

lighting. It has done so continuously<br />

for 100 years.<br />

About the Author: David L.<br />

DiLaura, Fellow IESNA (Member<br />

1968), has taught illuminating engineering<br />

at the University of Colorado,<br />

Boulder, for more than 20<br />

years. His development of mathematical procedures<br />

and lighting software programs—used universally<br />

by manufacturers and designers—laid the groundwork<br />

for lighting software used today. Prof. DiLaura<br />

recently published a translation of Johann Heinrich<br />

Lambert’s “Photometria” and is author of the new<br />

book, A History of Light and Lighting. A past IESNA<br />

Medal recipient, he also serves as the editor of LEU-<br />

KOS, the online journal of the IESNA.<br />
