<strong>Lincoln</strong> <strong>Laboratory</strong> Logo<br />

The <strong>Lincoln</strong> <strong>Laboratory</strong> logo, which first<br />

appeared in February 1958 in the <strong>Lincoln</strong><br />

<strong>Laboratory</strong> Bulletin, was conceived by Carl<br />

Overhage, the <strong>Laboratory</strong>’s fourth director.<br />

Overhage drew a Lissajous figure based on the<br />

superposition of two simple harmonic vibrations and<br />

commissioned retired Brigadier General Robert Steinle<br />

and the firm Advertising Designers of Los Angeles to<br />

transform the Lissajous figure into an artistic image.<br />

The two L’s rotated 180 degrees with respect to each<br />

other stand for <strong>Lincoln</strong> <strong>Laboratory</strong>. They form a rectangle<br />

enclosing the Lissajous figure generated by the parametric<br />

equations x = 3 sin(8πt/T ) and y = 4 sin(6πt/T ). The<br />

figure is traced along the horizontal axis x and the vertical<br />

axis y as the variable t progresses from t = 0 to T.<br />

The <strong>Lincoln</strong> <strong>Laboratory</strong> logo is an identifying symbol<br />

on <strong>Laboratory</strong> publications and its website. Because of its<br />

distinctive and striking appearance, it was included in the<br />

1972 edition of The Book of American Trademarks, a compilation<br />

of the nation’s most significant trademarks, logos, and<br />

corporate symbols.<br />

Lissajous Figure<br />

The Lissajous figure, familiar to most<br />

physical scientists and engineers, connotes<br />

harmony, order, and stability. The Lissajous<br />

figures, named for the French mathematician Jules-<br />

Antoine Lissajous, are also known as Bowditch<br />

curves after their discoverer, Nathaniel Bowditch,<br />

the mathematician from Salem, Massachusetts.<br />
