Dean Cornwell, The Other Side, 1918 (Saturday Evening Post)

Dean Cornwell

1892–1960 · United States

The "Dean of Illustration" who inherited the Brandywine method through Harvey Dunn, moved to London for five years to apprentice under Frank Brangwyn on the Los Angeles Public Library murals, and taught that the composition had to read as a finished abstract design from thirty feet before any figure reference was brought into the studio.

Signature moves

Resolve the picture as abstract before any figure

Held that "a good composition must be a good abstraction." Judged a thumbnail by whether it read as good composition at arm's length with no figurative detail visible. A thumbnail that did not hold as abstract design would not hold as finished picture.

Why it matters · The abstract structure is the first and most important decision. Painters who skip the abstract test produce paintings that depend on figurative interest to disguise weak composition.

Skip the charcoal underdrawing — start in tone and mass

Started directly in thinned oil paint, laying tonal masses with very large brushes (up to 3 inches wide for mural work). Stated principle: detail placed too early would calcify into "diagrams of the text."

Why it matters · Where Rockwell and most commercial illustrators began with detailed charcoal transfer, Cornwell started in paint. The detail is added to the abstract structure, not built from it. Painters who lock the figure first cannot recover the abstract design.

Move to London to find a studio big enough

For the 1927 Los Angeles Public Library mural commission (~1,500 sq ft, four panels), no New Rochelle studio could accommodate forty-foot canvases. Moved to London for five years (1927–1932) and worked from John Singer Sargent's former studio at 31 Tite Street, Chelsea.

Why it matters · A specific scale of work requires a specific scale of studio. Painters who try to do mural-scale work in illustration-scale studios cannot. The studio is infrastructure, and Cornwell relocated to find it.

Apprentice under Frank Brangwyn

During the London years also worked as Brangwyn's assistant on the House of Lords commission. Brangwyn taught the structural-color muralist doctrine: muralistic flatness as a virtue, subordination of figurative accuracy to compositional architecture.

Why it matters · The architectural mural is a different problem than the illustration. Cornwell sought out the apprenticeship rather than improvising. Painters who do not seek out specific masters for specific problems develop only what they could already do.

Develop a style the camera cannot supplant

Wrote in the 1940s, exactly as American illustration was industrializing around photographic reference: "Develop a style so far removed from the photographic standpoint the camera can't supplant you."

Why it matters · The painter's specific value is the interpretation that the camera cannot perform. Cornwell's position is the cleanest case for treating the painter's job as creative-interpretive rather than mechanically descriptive.

Recorded studio instruction

Sketch on location — drawing as superior to camera

Recorded advice to students: a precise pencil drawing made on location was "ten times more useful than a camera shot" — drawing forces the painter to select and internalize specific architectural or landscape information rather than accept the camera's indiscriminate record.

Why it matters · The pencil drawing is selective; the camera is comprehensive. The painter's discipline is in the selection. Drawing-based reference forces specific decisions; photographic reference defers them.

In the studio

Studio

Light: New Rochelle, New York (1915–1927). London at 31 Tite Street (Sargent's former studio, 1927–1932). New York again from 1932 onward.
Position: Standing, in disciplined blocks, at consistent pace.
Session length: Magazine illustration alongside mural campaigns. Up to several major color illustrations per month at peak.
Tools: Very large flat bristles for initial tonal lay-in (brushes up to 3 inches wide for mural work) · Sable rounds for figure resolution · Round bristle hogs for mid-scale work · Heavy Belgian linen for mural sections (combined in situ after painting) · Studio reference files of his own location sketches, costume studies, architectural drawings
Notes: Famous among students for the doctrine "discipline yourself — the things we do without discipline generally get us into trouble." Taught at Art Students League from late 1930s through 1950s. First American illustrator to successfully transition into large-scale public mural painting without abandoning the commercial illustration career.

Palette

Ground: Commercial primed linen for illustrations; fine Belgian linen of heavier weight for murals.
Whites: Lead white
Earths: Yellow ochre · Raw sienna · Burnt sienna · Raw umber · Burnt umber
Colors: Cadmium yellow · Cadmium orange · Vermilion · Venetian red · Madder lake · Viridian · Cobalt blue · French ultramarine
Blacks: Ivory black
Medium: Brangwyn principle — color served design, not representation. Mural is an abstract composition that contains figures; chromatic logic of design has to hold as pure pattern before figurative accuracy is added. Structurally saturated for readability at architectural distance.

Workflow, from blank canvas

1. The authentic idea
Specific compositional premise that organized the whole picture before any figure was placed. Abstract enough to survive translation into mural scale, specific enough to support narrative reading.
Why: An illustration begins not with a nice arrangement but with an authentic idea.
2. Thumbnail abstraction
Small compositional sketches — often a dozen or more — working out abstract structure. Judged by whether they read as good composition at arm's length with no figurative detail.
Why: A thumbnail that does not hold as abstract design will not hold as finished picture.
3. Pencil drawing on location
Precise pencil studies from models and from location sketching. Drawing-based reference always superior to photography.
Why: Drawing forces selection and internalization; the camera defers it.
4. Tonal lay-in (no charcoal)
"Lots of medium and very large brushes working entirely in tone and mass." Full picture blocked in tonally in the first session in heavily thinned oil paint to the point of complete value relationships within the first few hours of work, reading from thirty feet.
Why: No charcoal underdrawing. The painting starts in paint, in tone and mass, at the largest scale of brush the composition allows.
5. Figurative refinement
Only after the tonal abstract held. Brought in models for specific figurative resolution. Used the projected pencil studies as armature but worked figures out of the tonal ground-structure.
Why: Figures emerge from the tonal structure rather than being drawn on top of it.
6. Character finish
Sable rounds and smaller bristle brushes resolved specific character details — faces, hands, chromatic accents.
Why: Finish stage never violated the tonal structure established in stage 4.

Refusals — what they would not do

Refused charcoal underdrawing — started directly in paint, in tone and mass.
Refused photographic primary reference — drawing-based reference was always superior.
Refused stylistic dependence on the camera — developed a style the camera could not supplant.
Refused use of clippings of other illustrators' work — common shortcut he considered fatal.

Reference

Primary source: Sketching on location plus extensive personal files of own location sketches, costume studies, architectural drawings, organized by subject, period, region.
Photography: Used for specific problems: projected photographic studies of models for large mural figures where direct life posing at mural scale was not feasible; architectural photographs for historical buildings; period research photographs for costume authentication. Always supplementary, never primary.

Exceptions

Substantial primary-source historical research over years for the Los Angeles Public Library murals — archives, period documents, contemporary accounts.

Lineage

Teachers

Harvey Dunn · from 1915 — Art Students League of New York. Dunn had himself trained under Howard Pyle at Chadds Ford (1904–1906). Dunn's teaching at the Grand Central School of Art and the Art Students League was the principal conduit for the Pyle pedagogy into the post-Pyle generation. Through Dunn, Cornwell received the Brandywine doctrines in direct transmission from the Pyle source.
Frank Brangwyn · 1927–1932 — Five-year apprenticeship in London. Brangwyn taught the specific mural-design method — structural color, muralistic flatness as a virtue, subordination of figurative accuracy to compositional architecture. Cornwell assisted Brangwyn on the House of Lords commission during the same period. Inherited Brangwyn's position that "the best art is that which serves the best purpose."

Influences

Brandywine doctrine via Dunn (Pyle).
British muralist tradition via Brangwyn.

Students

Direct students from Art Students League teaching late 1930s–1950s: Harold Von Schmidt, Mario Cooper, Albert Dorne, Al Parker, John Gannam.
Many second-generation American illustrators carrying the Brandywine-Brangwyn method through the post-war era.
1946 instruction in Watson's Forty American Illustrators and How They Work is the principal printed source of his teaching doctrine.

Techniques and practices

Brandywine School

The narrative-illustration tradition founded by Howard Pyle at Chadds Ford, Pennsylvania, emphasizing dramatic lighting, direct observation, and living-in-the-subject.

Squaring Up from Studies

Transferring a small master sketch to a large canvas via a grid, preserving proportion across scale.

Lead-White Highlights

Reliance on lead white (flake white) for luminous, long-lasting highlights, especially on skin and metal.

Standing Practice

Painting while standing, on the belief that sitting flattens the energy of the mark and the range of the arm.

Costume and Prop Reconstruction

Sourcing actual period-accurate objects (clothing, weapons, furniture) and lighting them in the studio rather than inventing them.

If this painter is your match

You believe the composition has to hold as pure abstract pattern before any figure is placed — a painting that does not read as good design at thirty feet with the figurative detail blurred out will not read as good picture at full resolution either.

Borrow this: For your next major composition, refuse to use charcoal underdrawing. Start directly in paint, with the largest brushes you own, working entirely in tone and mass with heavily thinned medium. Spend the first full session bringing the canvas to a state that reads as complete abstract composition from thirty feet away.

Adjacent painters

Isaac Levitan1860–1900

The Peredvizhniki lyricist who invented the Russian mood landscape by trusting memory over direct observation and finishing paintings by knowing when not to touch them.

Ivan Kramskoy1837–1887

The intellectual strategist of the Peredvizhniki, whose studio ran on analytical silence, early photographic reference, and the conviction that a portrait was a biography rather than a likeness.

William-Adolphe Bouguereau1825–1905

The Parisian academic master who ran his studio on a factory schedule—7 AM until dark, no lunch break—and resolved every figure, every fold, and every leaf in preparatory studies before a single brushstroke landed on the final canvas.

Lawrence Alma-Tadema1836–1912

The Dutch-born Victorian archaeologist-painter who built a private library of five thousand photographs of Roman ruins, reconstructed marble and bronze from the actual excavations at Pompeii, and resolved every canvas as if he were producing forensic evidence that the ancient world looked exactly the way it did.

Shared the workbench

Other researched painters who used at least one of Cornwell’s techniques.

Howard Pyle1853–1911

The Wilmington illustrator and teacher who founded the Brandywine School, built the first serious atelier in American narrative painting, and transmitted three pedagogical principles—personal knowledge, the dramatic moment, paint the light and air—to N.C. Wyeth, Harvey Dunn, Frank Schoonover, and the whole golden age of American illustration.

N.C. Wyeth1882–1945

The Brandywine illustrator who inherited Pyle's doctrine of "personal knowledge"—rode the American West as a ranch hand for six months, filled a Chadds Ford studio with flintlocks, tomahawks, and authentic costume, and painted Treasure Island, Kidnapped, and The Last of the Mohicans as if he had been physically present at each scene.

Andrew Wyeth1917–2009

The Brandywine painter who inherited N.C. Wyeth's narrative training but abandoned illustration for egg tempera on gessoed panel, worked the same Pennsylvania farms and Maine houses for seventy years, and built each picture through thousands of cross-hatched tempera strokes over weeks or months.

Ilya Repin1844–1930

The Peredvizhniki history painter and portraitist who worked from zenith-lit studios, standing, from long social sittings, and painted monumental scenes from years of field observation.

Ivan Shishkin1832–1898

The Peredvizhniki landscape master who lived in the forest in summer and reconstructed its anatomy in the studio in winter, using photography and projection as tools of discipline rather than shortcuts.

Vasily Surikov1848–1916

The Peredvizhniki monumental reconstructionist, who built history paintings like buildings—over years, from authentic artifacts, trained crowds of real faces, and a structural drawing logic inherited from Pavel Chistyakov.
