to record a signer's signature. A small segment of the record could be removed and stored elsewhere to prevent misuse. The machine would then be able to mass-produce a template signature when needed. While the Robot Pen was commercially available, the first commercially successful autopen was developed by Robert M. De Shazo Jr., in 1942. De Shazo developed the technology that became the modern autopen in reference to a Request For Quote (RFQ) from the Navy, and in 1942, received an order for the machine from the Secretary of the Navy. This was the beginning of a significant market in government for the autopen, as the machines soon ended up in the offices of members of Congress, the Senate and the Executive branches. At one point, De Shazo estimated there were more than 500 autopens in use in Washington, D.C. Use Individuals who use autopens often do not disclose this publicly. Signatures generated by machines are valued less than those created manually, and perceived by their recipients as somewhat inauthentic. In 2004, Donald Rumsfeld, then the U.S. Secretary of Defense, incurred criticism after it was discovered that his office used an autopen to sign letters of condolence to families of American soldiers who were killed in war. Outside of politics, it was reported in November 2022 that some copies of The Philosophy of Modern Song, a book by singer-songwriter Bob Dylan that had been published earlier that month, had been signed with an autopen, resulting in criticism. Autographed editions had been marketed as "hand-signed" and priced at US$600 each. Both Dylan and the book's publisher, Simon & Schuster, issued apologies; refunds were also offered to customers who had bought autopen-signed editions. In addition, Dylan also said that some prints of his artwork sold after 2019 had been signed with an autopen, which he further apologized for and attributed his use of the machine to vertigo and the COVID-19 pandemic, the latter of which prevented him from meeting with staff to facilitate signing the works in question. U.S. Presidents It has long been known that the president of the United States uses multiple autopen systems to sign many official documents (e.g., military, diplomatic, and judicial commissions; some Acts of Congress, executive directives, letters and other correspondence), due to the volume of such documents requiring his signature per the U.S. Constitution. Some say Harry Truman was the first president to use the
