Soleiman Hayyim[1] (Persian: سلیمان حییم) (c. 1887 – February 14, 1970), was an Iranian lexicographer, translator, playwright and essayist, often called "Iran's Father of the bilingual dictionary".

[3] Hayyim started his education in a Maktabkhaneh (traditional type of elementary school) called Noor that belonged to Christian missionaries in Tehran.

[5][6][7][8] Soon after, he began working on the first series of bilingual dictionaries printed in Persian, a task that earned him the honorary name "Word Master."

[9][10] His first published work (1928) is a play, Yusof va Zoleikha, based on the story of Joseph and Potiphar’s wife Zuleikha, from the Old Testament.

Dariush Haim, Davood Adhami, Jahanguir Banayan, and Manouchehr Amiri have each written about their personal memories of Hayyim.
