Rafael Rivera, a Mexican scout, played a crucial role in Antonio Armijo's Spanish Trail expedition from Nuevo México in 1829. While leading a trader caravan group to Los Angeles, California, Rivera's scouting party ventured into unexplored territory in search of water. Within two weeks, Rivera discovered the Las Vegas Springs, which provided abundant artesian spring water and significantly shortened the Spanish Trail to Los Angeles. This discovery had a lasting impact, as evidenced by the naming of the Rafael Rivera Park, Community Center, and street in his honor. Furthermore, Nevada Historical Marker 214 commemorates his contributions to the region. Notably, 14 years after Rivera's discovery, John C. Frémont's expedition also camped at Las Vegas Springs in 1844, further solidifying the significance of Rivera's exploration.

Raphael Gray, a British computer hacker, gained notoriety at the age of 19 for orchestrating a global hacking spree, infiltrating computer systems and executing a multi-million pound credit card mission over six weeks. Utilizing an £800 computer purchased in his hometown of Clynderwen, Pembrokeshire, Wales, Gray exploited weak security in consumer websites, subsequently exposing the credit card details of over 6,500 cards. His audacious actions extended to sending Viagra tablets to Bill Gates' address and disclosing what he claimed to be the billionaire's personal number. However, Gray's brazen behavior led to his downfall when ex-hacker Chris Davis, offended by Gray's arrogance, tracked him down and provided his information to the FBI.

Despite his belief that law enforcers would be unable to catch him, Gray's actions ultimately led to his arrest and legal consequences.

Raphael Mitchel Robinson (1911-1995) was an American mathematician renowned for his contributions to mathematical logic, set theory, geometry, and number theory. He obtained his BA, MA, and Ph.D. from the University of California, Berkeley, and later married Julia Bowman, who became the first woman president of the American Mathematical Society. Robinson's work on undecidability and essential undecidability, particularly in collaboration with Alfred Tarski, significantly impacted the field of mathematics. Notably, he proved that an essentially undecidable theory need not have an infinite number of axioms, exemplified by his creation of the finitely axiomatizable Robinson arithmetic Q. Moreover, he delved into number theory, utilizing early computers for his research, such as coding the Lucas-Lehmer primality test. Robinson also made significant contributions to the study of plane tilings, simplifying complex theories in a remarkable 1971 paper. Throughout his illustrious career, he remained an active educator and prolific author, leaving a lasting impact on the mathematical community.Overall, Raphael Mitchel Robinson's pioneering work and scholarly contributions have solidified his legacy as a noteworthy figure in the field of mathematics, inspiring future generations of mathematicians and researchers.
