Feldman's father, and amateur painter, painted portraits and decorated the Eastern wall of synagogues. He brought in teachers to teach all of his children to play whatever musical instruments were available; he filled his garden with trees from all over the country and introduced an awareness of nature into the town, turning it into a floral expanse with avenues of cherries and other ornamental plants, during a period when nature and esthetics were far from the minds of most of the Jewish people.

Asher Feldman began drawing at age five, using elements that he found in nature to assist him with his art. His beloved mother passes away at around that time, and he overcame his grief by wandering in the woods, along the river back, and continually drawing and carving. He was always an uncompromising perfectionist, first and foremost with respect to his own work.

He set up a theatre in the town, working as a director, set designer, costume designer, and instructor, and he had the youth of the town enraptured. Most of the plays were taken from Bible stories, and the proceeds were donated to the Jewish National Fund.

Feldman studied at art schools in Rovno and Warsaw, He taught painting and art at the schools of the Tarbut organization, and wrote about didactics, methods of acting and composition, imparting knowledge of nature, engineering, development of the senses, etc. According to letters of thanks found in his daughter's collection, he was well loved by his pupils and headmasters at the Tarbut Schools. During Would War I, he served in the military, and in this capacity, worked on the restoration of palaces that suffered damage during the war, as well as of paintings and sculptures.

In 1923, he immigrated to Tibirias in Palestine, following his wife who was working there as a doctor. In 1925 the couple moved to Kfar Yehezkel. In Palestine, apart from painting, Feldman also researched the development of the Hebrew alphabet and its connection to ancient writing methods. He was assisted in this study of ancient sources by Prof. Dov Ashbel, who was a teacher in the village. The little hut which Feldman and his wife were given at Kfar Yehezkel was known as "The Palace" after Feldman renovated it, built furniture and covered it with patchwork upholstery.

In 1931, Bialik saw the work done on the alphabet and wanted to have it printed. He contacted the owner of a sophisticated printing press in Berlin and armed Feldman with letters of recommendation, but upheavals began in Germany and thus, this fascinating work, like many others, remained unpublished.

In 1924, Feldman participated in the well-known exhibition at the Tower of David.

In 1927, Feldman and his wife went to study in Paris, each in their own field At the end of the year, Feldman returned to his home country for a visit,  with an exhibition of views of the Holy Land. This exhibition made a great impression overseas, and editions of Hatsefirah newspaper from that period carry enthusiastic reviews. Most of the paintings were sold, particularly to priests and religious leaders. When they returned to Palestine, Feldman and his wife settled in Rehovot. There, Feldman taught at the only school that existed in that town at the period.

To this day, veterans of the town recall the play that Feldman put on with the children of the school in the large yard, with culture enthusiasts coming from far and wide by carriage and by foot. The play dealt with the story of Abraham and the Seraphim. All of the children in the school participated in preparations for the play and worked day and night with Feldman to set up the scenery, the costumes, and the musical accompaniment.

Feldman left teaching later on, but never got used to the scorn with which art and panting were regarded in Palestine during that period. He illustrated books published by the Omanut publishing house. These booklets contained stories of legends, festivals, animals, etc. His home contained cages housing snakes, lizards, porcupines, and birds which he was given, for the purpose of inspection, by Margolin, the director of the first zoo in Palestine. In 1929-1930 Feldman wandered the Judean desert, painting. He would spend whole weeks in the desert carrying a knapsack, a huge parasol, and a folding leather chair.

In 1935-1938, Feldman worked on a patent to preserve citrus  fruits. The invention was recognized as a registered patent (no 1411) by His Majesty's Government. The World War severed the communication required to implement the patent, and Feldman joined the British army, and lost interest in the patent. He had been more interested in the process - in the invention rather than in the business...

Upon his return from the military service, Professors Pozner and Haberscheim organized a solo exhibition for him in Rehovot. The exiled Polish National Theatre came to Palestine and Feldman was invited to prepare scenery for a play by Ostrovsky. Feldman worked night and day in an abandoned packing house in the middle of an orchard, and prepared scenery the likes of which had never before been seen in Palestine, full of imagination and special technical inventions. At this time, he also began working on an anatomic sculpture of the human form as a way of teaching anatomy, with each organ being capable of being taken apart and put back together, and each nerve, tendon, and gland styled and painted. This work was never completed, and only the upper part, the head and neck remain.

In 1965, an exhibition was organized for Feldman in Paris, which received rave reviews, among others, by the acclaimed art critic Christine Gleiny, who published a highly respected article on his work. Feldman worked in every possible field of creative endeavor, from sculpture, painting, carpentry, construction, gardening, sewing, cooking, animal husbandry, and any others. He could find a solution to any problem, and every solution was the outcome of in-depth study grounded in engineering, physics or chemistry, none of which he had ever learnt.

Feldman died of old age in 1975. He had lived in Israel for 53 years and his works include paintings of the scenery, inhabitants and ambiance of Israel 70 years ago, and during the years that followed.
