Otte Wallish (Hebrew: אוטה וליש; 1906–1977) was a Czech–Jewish artist and émigré to Mandatory Palestine who established himself as a graphic designer and contributed to the symbolic self-representation of the newly founded State of Israel as a Jewish state.

Born in Znojmo, Austria-Hungary, Wallish studied at the Academy of Fine Arts in Vienna before emigrating to Mandatory Palestine in 1934. He played a significant role in shaping the visual identity of the nascent State of Israel, most notably by designing the scroll for the Israeli Declaration of Independence and the country's first postage stamps, known as the Doar Ivri series. Wallish's work extended to various aspects of Israel's national symbolism, including the design of coins, banknotes, medals, and logos for major corporations. He also created posters promoting Zionism and Jewish immigration to Israel. His contributions to Israeli visual culture spanned from the pre-state period through the early decades of independence, making him a key figure in the development of Israeli graphic design and national iconography.

Otte Wallish was born in 1906 in the town of Znojmo, Moravia, at the time a crown land of the Austro-Hungarian Empire (today in the Czech Republic). He was a Czech of Jewish descent. He attended the Academy of Fine Arts in Vienna. After serving in the Czech army, he opened a graphic design and advertising office in Prague. He had jobs with the Jewish National Fund and United Israel Appeal. He married and then emigrated by boat to Mandatory Palestine in 1934, a time of increasing peril for European Jews. His wife joined him in 1935; a sibling survived the Holocaust and lived in the Czech Republic. The couple had two children and settled in a Herzliya house with Bauhaus furniture. He used the German Wallisch and, after moving to Israel, adopted the English Wallish transliteration of his name in Hebrew. (His first name is often incorrectly cited as Otto.)

During the 1930s and 1940s, Wallish worked on artistic arrangement, statistical graphs, and other design aspects for books. In 1929, his own book was published, ABC: Ein Bilderbuch. In 1936, Wallish set up a design studio in a building in Nahalat Binyamin, Tel Aviv, that had been chosen as a national landmark. His design studio doubled as a kind of front for SHA'I, the Haganah's secret service.

Wallish was responsible for the calligraphy and design of the scroll for the Israeli Declaration of Independence. Due to drafting debates beyond his control, Wallish had only finished the bottom part of the scroll by the time of the signing and announcement. In fact, David Ben-Gurion did not read the actual scroll but had to work from handwritten notes for the public declaration on 14 May 1948. The photograph shown here was taken by Wallish's brother-in-law, Rudi Weissenstein.

Wallish's scroll was prepared in three sections that were bound together. The original Declaration scroll is located in Israel's National Archives. He based the calligraphy style on a Torah scroll from the 16th century.

In addition, Walisch handled the preparation of the exhibit hall in which the State's Independence was announced. At the direction of Ben-Gurion and the immediate guidance of Ze'ev Sharef, Secretary of the National Administration, Wallish had the hall cleared of art not related to Jews and Israel. He had the hall's works exchanged for such works as Marc Chagall's Jew Holding a Scroll.

In 1948, too, Wallish took the lead in designing Israel's first postage stamps. He chose a design based on ancient coins, found in archaeological research on the First Jewish-Roman War and the Bar Kochba Revolt. He also designed the first day cover for the stamps' first usage on the first business day after Independence was declared, Sunday, 16 May 1948. Since the name of the state had not yet been determined during the design and secretive printing of the stamps, they were designed with the name Doar Ivri ("Hebrew mail") rather than Israel, the name found on all subsequent postage issues.
