Walter Graham Arader III is an American art dealer, focusing on rare maps, prints and natural history watercolors.
[2] His son, Walter Graham Arader IV, is married to British fashion writer Tatiana Hambro.
Two years later, his father, a Philadelphia businessman, former Pennsylvania Secretary of Commerce[4] and map collector, lent his son one hundred and fifty thousand dollars and Arader began to travel the antique-show circuit.
Such a method was used by Arader in the fall of 1985, when he bought the original watercolors for Pierre-Joseph Redouté’s masterpiece, Les Liliacées.
Sotheby's had planned to auction the flower watercolors one-by-one, but Arader created one of his syndicates and in a remarkable coup purchased the whole group with a single unchallenged bid of five million dollars.
