Carlos Manuel Echandi Lahmann (October 20, 1900 – August 23, 1938) was a Costa Rican surgeon murdered by Beltrán Cortés.

He married Julieta Brenes Hine with whom he had four children: Hilda, Olga (who died at a young age), Carlos Manuel and María Elena.

[2] He joined Hospital San Juan de Dios as an intern in 1926 and in late 1927 was named medical assistant to Dr. Moreno in surgery and orthopedics.

He would even later claim that he had gone to the hospital to get treated for a pain in his leg and that Dr. Moreno took advantage of this to take a graft of bone from his healthy arm for a foreign patient.

The ceremony was assisted by several government officials, members of the Costa Rican high society, and many common citizens.
