Born in Lisbon in 1950, Guilherme de Almeida graduated in Physics from the Faculdade de Ciências de Lisboa in 1978. He has also taught in this subject for 30 years.
He built his first telescope in 1966 and learnt all about the mechanics of producing and using telescopes through the 'Oficina de Óptica' of the Gulbenkian Planetarium.
For many years Guilherme has been helping to overcome the problem of making astronomy understandable and accessible to schools and the general public. His amateur astronomy meeting presentation, 'Naked Eye Guided Tour of the Sky' is well known and very popular.
Guilherme uses various telescopes, and makes regular observations with a Maksutov-Cassegrain 150 mm f/10, but he belives it is vitally important to get to know the night sky with the naked eye, before using optical equipment for observation.
