Elsie de Wolfe
The first modern decorator; she cleared the Victorian room and replaced it with light.
Verdict: Exemplar — the lesson in restraint applied to the Victorian room.
Elsie de Wolfe (1859–1950), later Lady Mendl, is generally credited as the first professional interior decorator. She began decorating commercially around 1905, eight years after Wharton and Codman's The Decoration of Houses had been published. She had read it.
The Colony Club commission (1905) — the first all-women's social club in New York — was her breakthrough. She replaced the expected dark panelling and heavy drapes with pale chintzes, white paint, trellis-work, and good light. The reaction was a mixture of bafflement and recognition. She had, in effect, demonstrated Wharton's thesis in three dimensions: clear the ornament, resolve the proportion, let the room speak.
De Wolfe's method, developed over decades in New York, Paris, and at her villa at Versailles, distils to a short set of principles continuous with Wharton's argument: light before atmosphere, proportion before decoration, comfort before display. Her own formulation — "I believe in plenty of optimism and white paint, comfortable chairs with lights beside them, open fires on the hearth" — sounds effortless, which is the point. The room that appears effortless has had its effort directed at the right things.
The Victorian Foil
The standard Edwardian interior against which de Wolfe worked was defined by accumulation: heavy curtains that absorbed light, floors covered in competing patterns, every surface carrying objects chosen for their independent interest rather than their relation to the room. De Wolfe's achievement was not a new style; it was the application of existing architectural principles — those that Wharton had articulated — to the actual rooms that people lived in.
The restraint was not minimalism. Her rooms were comfortable, inhabited, full of colour and pattern. What was absent was the Victorian error: accumulation without regard for scale, decoration without regard for proportion. Everything in a de Wolfe room had to earn its place. This is the same discipline the wiki applies to the wardrobe.
The Lesson
The first modern interior decorator is notable not because she invented a style but because she cleared the air. Her contribution was the demonstration that the Victorian interior was a problem of principle: the rooms that failed did not fail because they were cheap but because they were filled before they were understood. De Wolfe understood the room first, and then — only then — considered what to put in it.
