On June 1, 1872, the U.S. Congress passed the Organizing Act, which established the Centennial Board of Finance to raise funds for the U.S. Centennial International Exhibition of 1876 in Philadelphia. The Board was tasked with selling stock to fund the fair, setting a firm deadline of June 1, 1875, to process all stock subscription requests. One notable purchase was by Samuel Pennypacker's grandfather Joseph R. Whitaker, who bought 10 shares at $10 each, receiving a certificate adorned with engravings of American history. This effort successfully raised the necessary $10 million to finance the grand event, which opened in Fairmount Park on May 10, 1876. Celebrating the nation's centennial, the exposition featured technological marvels like Alexander Graham Bell's telephone and Thomas Edison's telegraph system, along with cultural exhibits such as Heinz ketchup and the Statue of Liberty's torch. Attracting nearly 10 million visitors, this world's fair highlighted America's innovations and cultural prowess, leaving a lasting legacy.
