After the spacecraft Mariner 9 provided extensive imagery of Mars in 1972, a small crater (later called Airy-0), located in the Sinus Meridiani ('Middle Bay' or 'Meridian Bay') along the line of Beer and Mädler, was chosen by Merton Davies of the RAND Corporation to provide a more precise definition of 0.0° longitude when he established a planetographic control point network.
Founded in 1856 in Offenbach, Germany, a suburb of Frankfurt considered to be the "leather capital of Germany" since the mid-1800s and has been the head office to other coveted German brands such as Seeger (founded in 1889) and Mädler (founded in 1850).
In 1830, Beer and Mädler created the first globe of the planet Mars.
