Eight years ago Darleen Bungey published a revelatory biography of Arthur Boyd. She cast shadows across the ‘idyllic’ Open Country years where the extended Boyd family lived in suburban Murrumbeena and unflinchingly detailed his declining, alcoholic years at Bundanon. Bungey’s compelling new biography of John Olsen has its share of revelations. Olsen’s weak and inadequate father wound up destitute on the streets of Sydney, largely sustained by handouts from his son. Boyd was an intensely private man, friendly but reclusive. Olsen has been a public figure for most of his long career, reaching back to the early 1950s when he emerged from the Julian Ashton school as the star student of the difficult and demanding John Passmore. Boyd was dead before Bungey published her biography. John Olsen, happily, remains a boisterous octogenarian, going strong in art and life. A living subject is not always to the biographer’s advantage. Bungey can sound like a cheerleader: ‘Like Jay Gatsby, John was a man from an impoverished childhood with a mind for enquiry, a hunger for romance and a need for invention.’

The cover assembles the book’s title and author’s name (writ very large) with a photograph of him, in an art gallery, before a wide yellow landscape by Fred Williams. Turning to the viewer, Patrick McCaughey is about to launch into a story that will satisfy the curiosity teased by the name of the book, Strange Country: Why Australian Painting Matters.

Picasso at twenty-five was famous in Paris, comfortably off by 1914, wealthy and internationally recognised six years later. He married a leading ballerina, Olga Khokhlova, in Serge Diaghilev’s Ballets Russes. It turned out badly. Two of his mistresses, Fernande Olivier and FranÇoise Gilot, wrote tell-all memoirs, which he did his best, unsuccessfully, to repress. At least two other mistresses, Marie-Thérèse Walter and Dora Maar, have attained independent fame through his manic and magic portraits of them. He became a communist during World War II but was hooted down by the party when he drew Uncle Joe as a mustachioed gallant. He died in 1973 at the age of ninety-one after a tumultuous final decade of work. John Richardson and Marilyn McCully are engaged in a multi-volume biography, which, after three substantial tomes, has brought the story up to 1933.

Roy Strong was appointed director of the National Portrait Gallery (NPG) in 1967 at the age of thirty-two. Today it would be astonishing to head one of the United Kingdom’s national collections at that age; five decades ago it was outrageous. Only Kenneth Clark at thirty was younger when he became director of the National Gallery. Strong’s ascent to the NPG has stayed in his mind as the fulcrum of his professional life.

Despite its unrewarding title, The Steins Collect, both exhibition and catalogue, tells the most captivating story of early modern art and its patronage. The cast of characters ranges from the downright difficult (Leo) and the overweeningly self-important (Gertrude) to sunny Californian idealists (Sarah and Michael). Gertrude and her brother Leo set up their joint ménage at 27 rue de Fleurus, close to the Luxembourg Gardens, in 1903. A year later, Michael, their elder brother, and his wife, Sarah, settled in Paris and lived close by at 58 rue Madame. By 1909 the two households had assembled the largest and finest collection of Matisse and Picasso anywhere. Though comfortably off, the Steins were not remotely among the super-rich, yet only the Russian collectors, Sergei Shchukin and Ivan Morozov, at the end of the decade, would challenge their supremacy.
