Albert Einstein’s patents

This paper presents a review and description of the patents of the 20th century scientist and philosopher Albert Einstein. The patents produced in collaboration with very prolific inventors cover the period of 1928–1936. Einstein’s patents included refrigerators, electromagnetic pumps, sound reproduction apparatus and light intensity self-adjusting cameras. This paper illustrates that patents are a valuable source of information for constructing historical profiles of Einstein’s colleagues. The paper concludes that the 20th century theories of Einstein continue to be an exceptionally valuable source of patentable ideas.
