Released on January 4, 1972, the HP-35 from Hewlett-Packard marked a significant milestone as the world's first scientific calculator compact enough to slip into a shirt pocket, specifically Bill Hewlett's. This pioneering device quickly gained popularity among students, engineers, and scientists alike. Despite its substantial price tag of $395 at the time (equivalent to over $2,200 today), the HP-35 exceeded sales projections by tenfold in its inaugural year.
