Born in Huși, Fălciu County (present day Vaslui County), Romania, Giugaru began his stage career in 1916 after graduating from school in Cuza Vodă and studying at the Conservatory of Dramatic Arts in Bucharest.
After performing on various stages in Romania — including the National Theatre in Bucharest — he made the transition to film in 1925's Năbădăile Cleopatrei.
His last film role before retirement was in 1968's Răpirea fecioarelor, directed by Dinu Cocea and starring Toma Caragiu and Marga Barbu.
[1] For his work on stage and film Giugaru obtained the title of Emeritus Artist and the State Prize in 1964.
In 2004, his daughter Alexandrina brought accusations of "piracy" against Societatea Română de Televiziune for using images of her father and his voice to promote the television station.
