Biography
Sunset in Öland
Sunset

His father was a house painter. He took drawing lessons as a child, then studied at the Royal Swedish Academy of Fine Arts from 1865 to 1872, but was influenced by French painting rather than the prevailing Düsseldorf School. In 1876, thanks to the support of King Oscar II, he was able to go to Paris, where he lived until 1890. There, he came under the influence of the Barbizon School and Camille Corot. His first exhibit at the Salon was in 1878 and he won a gold medal at the Exposition Universelle (1889).

After returning to Sweden, he lived in Öland, then Stockholm. On the advice of art collector and merchant Pontus Fürstenberg who was a major patron of the arts, he settled in Gothenburg in 1891. He continued, however, to visit Öland every summer and opened a studio in Birger Jarls Bazar, one of Stockholm's first modern office buildings. As the 1890s progressed, he began to work in a style known as mood impressionism (stämningsimpressionism). His favorite places for painting were Stockholms ström and Jämtland. His home was a meeting place for the local cultural and academic world; including the writer, August Bondeson and the painters, Georg and Hanna Pauli. [2] [3]

He also seems to have slowly become rather blasé regarding his work. In the Artists' Association (Konstnärsförbundet), he was known as "Pekström" and, under criticism from Karl Nordström and Nils Kreuger, his standing there diminished. His submission for the Exposition Universelle (1900) was rejected by the jury.

He served as inspiration for the painter, Sellén; a character in The Red Room by August Strindberg. The largest collection of his works may be seen at the Nationalmuseum, the Göteborgs konstmuseum[4] and Prins Eugens Waldemarsudde[5].

A street in Södra Ängby (Per Ekströms väg") is named after him. Until 2012, there was a privately owned Per Ekström Museum in the Kalmar konstmuseum . The following year, it was moved into the old Orrefors glassworks building and expanded to include other artists.[6] Per Ekström Society (Per Olof Ekströmsällskapet) was founded in 2016 and chaired by the art historian, Ulf Abel. [7]

Personal life

In 1904, he married Hanna Petronella Salomonsson, the daughter of a farmer in Alvesta. In 1910, they moved to the island of Öland. He died during 1935 at Mörbylånga on Öland.

  • Sunset (1904)
  • French landscape (1878)
  • Gräsgård Church (1922)
gollark: So this is a mess. PotatOS is actually shipping a mildly different ECC library with a different curve because steamport provided the ECC code ages ago.
gollark: I mean, what do you expect to happen if you do something unsupported and which creates increasingly large problems each time you do it?
gollark: <@151391317740486657> Do you know what "unsupported" means? PotatOS is not designed to be used this way.
gollark: Specifically, 22 bytes for the private key and 21 for the public key on ccecc.py and 25 and 32 on the actual ingame one.
gollark: <@!206233133228490752> Sorry to bother you, but keypairs generated by `ccecc.py` and the ECC library in use in potatOS appear to have different-length private and public keys, which is a problem.EDIT: okay, apparently it's because I've been accidentally using a *different* ECC thing from SMT or something, and it has these parameters instead:```---- Elliptic Curve Arithmetic---- About the Curve Itself-- Field Size: 192 bits-- Field Modulus (p): 65533 * 2^176 + 3-- Equation: x^2 + y^2 = 1 + 108 * x^2 * y^2-- Parameters: Edwards Curve with c = 1, and d = 108-- Curve Order (n): 4 * 1569203598118192102418711808268118358122924911136798015831-- Cofactor (h): 4-- Generator Order (q): 1569203598118192102418711808268118358122924911136798015831---- About the Curve's Security-- Current best attack security: 94.822 bits (Pollard's Rho)-- Rho Security: log2(0.884 * sqrt(q)) = 94.822-- Transfer Security? Yes: p ~= q; k > 20-- Field Discriminant Security? Yes: t = 67602300638727286331433024168; s = 2^2; |D| = 5134296629560551493299993292204775496868940529592107064435 > 2^100-- Rigidity? A little, the parameters are somewhat small.-- XZ/YZ Ladder Security? No: Single coordinate ladders are insecure, so they can't be used.-- Small Subgroup Security? Yes: Secret keys are calculated modulo 4q.-- Invalid Curve Security? Yes: Any point to be multiplied is checked beforehand.-- Invalid Curve Twist Security? No: The curve is not protected against single coordinate ladder attacks, so don't use them.-- Completeness? Yes: The curve is an Edwards Curve with non-square d and square a, so the curve is complete.-- Indistinguishability? No: The curve does not support indistinguishability maps.```so I might just have to ship *two* versions to keep compatibility with old signatures.
