IHOF Nomination Leonard Bosack – Nomination #552

Impact (200 words)

Leonard Bosack, Sandy Lerner, and Kirk Lougheed launched Cisco in 1984, growing the Internet’s backbone—$224 million IPO by 1990 (Cisco stats). From Stanford, their 40-year push (1984–present) scaled multiprotocol routing—5.3 billion users (2023, ITU)—35 million-line browsers rely on their infrastructure. Cisco’s routers enabled seamless data exchange across diverse networks, standardizing global connectivity. Their open routing protocols, like RIP and OSPF, fostered interoperability, ensuring the Internet’s accessibility worldwide. This infrastructure powered the web’s expansion, from universities to enterprises, connecting disparate regions like Africa and Asia. By 2023, Cisco held 41% of the router market (IDC), underscoring its role in the Internet’s evolution. Their work advanced the Internet’s global nature, making it a scalable, open platform for communication and commerce, foundational to modern digital ecosystems.
