Louis Diat

{{quote box|width=26em|salign=right|quote=Born in France ... naturalized thirty years ago as an American citizen ... ardently democratic in his sympathics today ... M. Diat is one of the most famous among the clever chefs of America. He is a tall, slender, courtly man—very handsome with his iron-gray hair, heavy black brows, and dark, luminous eyes. Kindly, diffident in manner, he is nevertheless an exacting boss over the maze of kitchens, pantries and storerooms and the small army that mans them. He is also an enthusiast for American food.{{cite news|url=https://www.latimes.com |title=Meat ...

At age five, Diat learned to cook. At age eight, he awoke early before school to cook soup. He observed the cooking of his mother and grandmother.{{cite news|url=https://www.nytimes.com |title=News of Food; Chef Louis Diat Recommends New Dish On Ritz-Carlton Summer Garden Menu |date=21 May 1947 |newspaper=The New York Times |page=22 |access-date=7 December 2010 |archive-url=https://www.webcitation.org/62MQI5Viu?url=http://hn.bigchalk.com/pqdocs/share4/pqimage/hnirs103v/201110111425/33082/5669/out.pdf |archive-date=11 October 2011 |url-status=dead }} His mother taught him tarts, while his grandmother demonstrated how to broil chicken over charcoal. By age 13, Diat resolved to become a chef, and by 14, he entered into an apprenticeship in a Moulins patisserie.

At 18, he spent tours of duty at Paris' Hôtel Le Bristol Paris and L'Hotel Du Rhin. Diat was appointed chef potager (soup chef) in 1903 at Hôtel Ritz Paris. In 1906, at 21, he transferred to The Ritz Hotel London, where he held the same position and also aided the main sauce maker. At both locations, Diat was coached by founder César Ritz.{{cite news|url=https://pqasb.pqarchiver.com/courant/access/921455692.html?dids=921455692:921455692&FMT=ABS&FMTS=ABS:Al |title=U S Women Can't Cook, Says Chef |last=Roe |first=Dorothy |date=7 October 1945 |newspaper=The Hartford Courant |page=SM9 |archive-url=https://www.webcitation.org/62MQSXaaN?url=http://hn.bigchalk.com/pqdocs/share4/pqimage/hnirs103v/201110111428/24208/5628/out.pdf |archive-date=11 October 2011 |url-status=dead }}

On October 8, 1910, aged 25, Diat immigrated to New York, becoming the chef of Carlton House on 23 October 1910 and about 7 weeks later the head chef of the newly opened Ritz-Carlton in Manhattan. The first week of November, Diat applied to be a citizen of the United States. Diat served as the chef de cuisine at the Ritz-Carlton's roof-garden restaurant. Auguste Escoffier oversaw the inauguration of the restaurant. Diat invented a novel recipe every summer for the sultry climate.{{cite news|url=https://www.nytimes.com/1955/07/04/archives/news-of-food-ritz-chef-fresh-suggestions-still-emerging-from.html |title=News of Food: Ritz Chef; Fresh Suggestions Still Emerging From Kitchen of Retired Mr. Diat |date=4 July 1955 |newspaper=The New York Times |page=14 |access-date=6 December 2010 |archive-url=https://www.webcitation.org/62MQW1Dw7?url=http://hn.bigchalk.com/pqdocs/share3/pqimage/hnirs104v/201110111429/16436/30020/out.pdf |archive-date=11 October 2011 |url-status=dead }}

During his 41-year stint at the Ritz-Carlton, he cooked for King Edward VIII as the Prince of Wales; other nobles like queens, prime ministers, and ambassadors;{{cite news|title=Harvard in Hotel Business; Inherits New York's Ritz|date=12 July 1941|newspaper=Boston Daily Globe|page=14|location=New York}} {{subscription required}} and on one occasion, the exclusive wine club Confrérie des Chevaliers du Tastevin ("Knights of the Wine Cup").{{cite news|url=https://www.nytimes.com/1948/05/30/archives/with-champagne-and-burgundy.html |title=With Champagne and Burgundy |last=Nickerson |first=Jane |date=30 May 1948 |newspaper=The New York Times |page=SM28 |access-date=6 December 2010 |issn=0362-4331 |archive-url=https://www.webcitation.org/62MQZBGN5?url=http://hn.bigchalk.com/pqdocs/share3/pqimage/hnirs101v/201110111430/03176/15106/out.pdf |archive-date=11 October 2011 |url-status=dead }} He "worked fourteen hours a day, six days a week, and spent seven or eight hours at the hotel on Sunday, his day off". According to Lawrence, Diat was the supervisor of 150 chefs. "Formidable" yet benign, Diat served as the kitchen mediator and first aid expert in the case of injuries. Diat forbade the use of substitutes in food, and rejected the proposition of a canned version of vichyssoise.

Diat typically reached his office by 8:15 am and spent slightly over an hour ordering goods. For the remainder of the morning, he supervised and advised his kitchen staff and confirmed the menus. In the afternoon, he wrote in his office.

Diat taught cooking classes in the kitchens. Some of his students became chefs at other hotels in New York, Washington, D.C., and Colorado. Diat received a visit from the president of the Campbell Soup Company, Arthur Dorance, who stayed at the Ritz for half a year to learn Diat's soup making techniques. In 1938, Diat won the distinguished Chevalier du Mérite Agricole "for having done so much to bring an important element of culture and civilization to the United States". In 1947, Diat became the in-house chef of Gourmet.{{cite book|last1=Reichl|first1=Ruth|last2=Stewart|first2=Zanne Early|last3=Willoughby|first3=John|title=The Gourmet Cookbook: More Than 1000 Recipes|url=https://books.google.com/books?id=D7IhN7lempUC|year=2006|publisher=Houghton Mifflin Harcourt|location=Boston|isbn=0-618-80692-X|page=82}}{{cite magazine|url=https://books.google.com/books?id=5sXyAAAAMAAJ|title=Gourmet|year=2006|magazine=Gourmet|volume=66|issue=7–9|page=126|access-date=13 December 2010|publisher=Condé Nast Publications|quote=In 1947, LOUIS DIAT ("Tomatoes," page 135) of The Ritz-Carlton became gourmet's in-house chef ...}} Diat was included in a list of chefs with annual salaries of $10,000 to $25,000.{{cite news|url=http://imgcache.newsbank.com/cache/ean/fullsize/pl_012072010_1723_15193_900.pdf |title=Chefs Draw Big Salaries |date=8 December 1922 |newspaper=The Kansas City Times |volume=43 |issue=82 |page=32 |access-date=7 December 2010 |location=Kansas City, Missouri |archive-url=https://www.webcitation.org/5uoAixq6Z?url=http://imgcache.newsbank.com/cache/ean/fullsize/pl_012072010_1723_15193_900.pdf |archive-date=7 December 2010 |url-status=dead }}

Vichyssoise was served the rest of the summer and the following summers. During the colder seasons, he did not include it in the menu, but so many people asked for it, in 1923, Diat placed it on the menu full-time. Diat recalled that Sara Roosevelt had had vichysoisse and "once called me up at five in the afternoon and asked me to send eight portions to her house".

When Diat had no access to leeks in his cooking, his vexation prompted the produce stocker to find a Long Island farmer to cultivate a small yield.{{cite news|url=https://news.google.com/newspapers?id=0oEyAAAAIBAJ&pg=6947,338408|title=Classical Recipes Feature The Flavorful Elegance Of Leeks|last=Larsen|first=Ted|date=3 June 1987|newspaper=Lawrence Journal-World|page=3C|access-date=8 December 2010}}

Diat and his wife Suzanne had one child, a daughter, Suzette. Between 1916 and 1929, the family lived in New Rochelle, N.Y. Between 1929 and January 1950, they lived in a small apartment on Manhattan's Central Park West. Thereafter, Diat and his wife lived in Hartsdale, in Westchester County, N.Y.

Suzette Diat married George J. Lawrence, with whom she had two children. In an interview, Suzette Diat Lawrence described her father as "a gentle, humble man, simple in his tastes. ...  He enjoyed good cooking. It didn't have to be fancy as long as it was prepared well without too much seasoning and not too rich". She considered her father a patient instructor, "He would answer any question concerned with cooking. He had no secrets." Additionally, Diat "taught his family the art of using leftovers" to create new dishes.{{cite news|url=https://pqasb.pqarchiver.com/latimes/access/661511782.html?dids=661511782:661511782&FMT=ABS&FMTS=ABS:AI |title=Creme Vichyssoise Glacee |last=Hansan |first=Barbara |date=17 December 1970 |newspaper=Los Angeles Times |issn=0458-3035 |archive-url=https://www.webcitation.org/62MPfp87a?url=http://hn.bigchalk.com/pqdocs/share4/pqimage/hnirs102v/201110111416/18240/13677/out.pdf |archive-date=11 October 2011 |url-status=dead }}

Diat's two brothers also distinguished themselves in the culinary field. Jules Diat was a teacher. His son (Louis's nephew) was chef saucier (sauce chef) at the 1939 New York World's Fair. A participant in the French Resistance during World War II, he was killed by the Germans. Lucien Diat, younger than Louis by seventeen years, was the renowned executive chef at Plaza Athénée hotel in Paris and also the teacher of Jacques Pépin.Jacques Pépin, The Apprentice: My Life in the Kitchen (New York: Houghton Mifflin 2004), p. 88.

In Louis Diat's French Cookbook for Americans,{{#tag:ref|This was published in 1946 by J. B. Lippincott & Co. and later renamed to Home Cook Book: French Cooking for Americans|group=note}} Diat compared cooking in the United States with cooking in France. He noted that the key to cooking is appeal. "[Americans] could do it as well as the French, but one has to be interested. In France girls of 11 already are able to prepare meals from watching and helping their mothers. It's early training that does it". Diat proceeded to discuss meat, gravies, fish, and salads. Finally, he added that "fine cooking is the basis of a happy life ... Men like to eat well ... so if you want to keep your husband home, learn to be a good cook." Many of the recipes in this book are derived from the meals Diat's mother cooked.{{cite news|url=https://www.latimes.com/archives/la-xpm-1992-05-07-fo-2201-story.html |title=Home Cook: The Grandmother of Vichyssoise |last=Cunningham |first=Marion |date=7 May 1992 |newspaper=Los Angeles Times |page=25 |access-date=30 November 2010 |archive-url=https://web.archive.org/web/20211017213131/http://articles.latimes.com/print/1992-05-07/food/fo-2201_1 |archive-date=17 October 2021 |issn=0458-3035 |url-status=live }} {{subscription required}}

Diat alleged that American women cannot cook since they "often ruin good food trying to save" money or time. In response to this dilemma, Diat wrote a book entitled La Cuisine de Ma Mère to divulge all his "cooking secrets". Diat suggests that they "approach their cooking with imagination, interest and an eye for artistic effects".{{cite news|url=https://news.google.com/newspapers?id=7DAvAAAAIBAJ&pg=4164,1502252|title=Famous Chef Gives Pointers On Glamorizing Summer Food|date=14 June 1949|publisher=The Owosso Argus-Press|page=10|access-date=8 December 2010|location=New York}} Ascribing his culinary finesse to his mother, Diat dedicated the book to his mother, "Annette Alajoinine Diat, who guided the early years, inspired the later ones and whose memory is still a spur".

In Sauces: French and Famous (1951), Diat discussed how to make the sauces bechamel, brown sauce, tomato sauce, and mayonnaise. He also included a narration of his eating habits. Diat also wrote French Cooking for the Home (1956) and Gourmet's Basic French Cookbook (1961).

Louis Diat was also depicted in Season One, Episode 23 of popular anime series Food Wars!, where he is referenced due to his creation of vichyssoise. {{Cite web|last=SenpaiNEWS|first=Team|date=2019-01-03|title=Season 1, Episode 23 of Food Wars!
