Alberto Greco (January 15 1931 – October 12 1965) was an Argentine artist who was instrumental in the development of conceptual art in Argentina, Brazil, and Spain.

His best-known artwork is a series called Vivo Dito in which Greco draws attention to objects and people as living art pieces within everyday life.

[5] Informal art explored possibilities of gestures and materialism that were typically non-traditional, and signage as the basis of communication.

"[3] Alberto Greco frequently expressed his desire for personal and artistic growth, which he linked to erasing societal prejudice.

Because of Greco's response to people's words and his ways of excluding prejudice, he became a symbol of the liberating angel to the marginalized.

"[3] Greco frequently referenced themes of hope and rebellion in his work, connecting them to broader societal and personal struggles.

Like an unbalanced scale, he would often go from smoking cigarettes on the street to being waited on by maids in odd environments such as parks or gardens.

[7][8] Greco once wrote a manifesto on a scroll and strung it around the town, calling it "Gran Manifiesto- Rollo Arte Vivo Dito".

Some accounts suggest that Greco once drew a circle around a man during his Vivo Dito project, symbolically trapping him within the artwork.

"[3] Greco described Vivo Dito as a living art form, emphasizing its role as a dynamic and evolving concept.

[4][10] Greco often compared a finished project to a dead object; when something dies you do not go to its grave and dig it up to change its appearance or add to it, you simply let it rest, as you should to your artwork.

[3] Not too long afterward, Greco’s unconventional art involving live mice reportedly caused issues at a hotel due to complaints about odor.

Some of his art had political influences, such as his piece about President Kennedy's assassination during Greco's "Sin Titulo Series".

This type of drug is meant to repress the activity of the central nervous system reducing anxiety, but impairing memory and judgment at the same time.

[12] Greco emphasized the importance of big gestures and overdramatized performances; in his mind, that was the only way to convey his ideas.

[3][4] Greco's final actions have been interpreted as an attempt to convey his artistic vision in an impactful way.
