[3] The opening of one of her operas, Schiava et Regina, had to be postponed due to the bombing of the Gran Teatre del Liceu by anarchists.

[2] The family owned multiple properties, including a vacation house in Sitges and in Badalona, where Casagemas and Picasso spent time together.

Casagemas formed strong political views during his teenage years becoming a self-declared anarchist and a Catalanista (Catalan nationalist), even taking part in demonstration and having a run-in with police.

The two quickly became close friends,[3] traveled around Spain together, and then shared a studio on Carrer Riera de Sant Joan in Barcelona at the beginning of 1900.

[4] One of the three oil paintings exhibited in that show, entitled Last Moments, was selected to be included in Paris's Exposition Universelle.

(Last Moments no longer exists in its original form, having been painted over by Picasso in 1903 as La Vie, an allegorical work featuring Casagemas.)

Casagemas also put up an exhibit at Els Quatre Gats just after Picasso's, in late March and early April 1900.

[4] Casagemas spoke of suicide often and attempted to kill himself at least once before Picasso suggested that they leave Paris and return to Spain for the holidays.

In 2014, the National Art Museum of Catalonia (Museu Nacional d'Art de Catalunya, MNAC) put up the first major exhibit dedicated solely to Casagemas's work.

[11][2] Robert Sheehan portrayed Casagemas in the 2018 season of the television series Genius, which focuses on the life and career of Pablo Picasso.
