Researching for information about the Mejía brothers, I found out they were the children of Sara Duke and Federico Mejía. It was in a local newspaper that I found out a name related with that family. The news was about a Salvadoran high society lady who said she was raised by Sara Duke. I looked in the phone book and I found her daughter's phone number. She gave me her mother's number.
I remember my conversation with this old lady because I happened to call her around eight o'clock, at night. Apparently, I interrupted her favourite TV program. It was a interview program ran by a journalist that months later would become president of El Salvador. I understood she follow that program with eager. So She told me to call her next day.
I called her and she bombarded me with information. But when I tried to make an appointment for a personal interview with her, she said it would be better to talk to her cousin. Her cousin happened to be Federico Mejía's daughter.
I made an appointment with Federico's daughter. I visited her at her house. In the living room she had a mandolin which belonged to her father.
I took the detail of carrying with me her father's pictures. RPI's archivist had sent to me a picture where the Mejía brothers were portrayed as part of a mandolin club.
ELECTRICAL ENGINEERING IN THE 1910s.
Electrical engineering has changed tremendously in the past one hundred years. RPI sent me the electrical engineering program that they had back in the 1910s.
We still do not know how this two electrical engineers, educated in New York, influenced the development of the Salvadoran college of engineering. I have collected some information but still it is small and sparce.
