The HP Garage is a private museum where the company Hewlett-Packard (HP) was founded. It is located at 367 Addison Avenue in Palo Alto, California. It is considered to be the "Birthplace of Silicon Valley". It is a designated California Historical Landmark and is listed on the National Register of Historic Places.
The home, originally designated as 367 Addison Avenue, was first occupied in 1905 by Dr. John Spencer, his wife Ione, and their two adult daughters. Dr. Spencer was selected as the first mayor of Palo Alto in 1909. In 1918 the house was divided into two separate apartments, numbered 367 and 369.
In 1938, newly married Dave and Lucile Packard moved into 367 Addison Ave, the first floor three-room apartment, with Bill Hewlett sleeping in the shed. Mrs. Spencer, now widowed, moved into the second floor apartment, 369 Addison. Hewlett and Packard began to use the one-car garage, with $538 in capital.
In 1939 Hewlett and Packard formed their partnership, with a coin toss creating the name Hewlett-Packard.
Hewlett-Packard's first product, built in the garage, was an audio oscillator, the HP200A. One of Hewlett-Packard's first customers was Walt Disney Studios, which purchased eight oscillators to test and certify the sound systems in theaters that were going to run the first major film released in stereophonic sound, Fantasia.
The HP garage is not open for public tours, but the property can be viewed from the sidewalk and driveway.
The 1982 movie Tron contains a possible reference to the HP Garage. In a scene between the characters Dillinger and ENCOM founder Gibbs, the following dialogue occurs: Dillinger: This isn't the company you founded in your garage. Gibbs: Sometimes I wish I was back in that garage.
