**Álvaro Wille Trejos** (May 17, 1928 – June 11, 2006) was a renowned Costa Rican entomologist celebrated for his extensive research on the insects of Central America, with a particular focus on bees. Born in San José, Costa Rica, Trejos exemplified the qualities of a Generator in Human Design, characterized by his ability to respond to the needs of his environment and a deep passion for his work. His Sacral Inner Authority guided him through challenges, enabling him to thrive in the field despite the dangers posed by illegal mining in the Costa Rican jungle.

Trejos’s dedication to fieldwork is epitomized by his pioneering study of Corcovado, a region rife with ecological significance yet fraught with peril. His commitment to understanding and preserving this unique ecosystem often put him in life-threatening situations, underscoring his courage and determination. As a 2/4 Profile, he was naturally inclined to seek solitude and introspection, which fueled his innovative ideas, while also building meaningful connections within his community.

His Incarnation Cross, the Right Angle Cross of Contagion (8/14 | 30/29), reflects his ability to inspire and influence others through his findings and passion for entomology. Trejos’s legacy continues to thrive through the Doctor Álvaro Wille Trejos Center for Community Studies and Empowerment, established in his honor by the Neotrópica Foundation on the Osa Peninsula near Corcovado National Park. This center embodies his commitment to community engagement and environmental stewardship.

Álvaro Wille Trejos’s life and work remain a testament to the profound impact of a dedicated researcher whose Human Design attributes shaped his journey and contributions to science.
