There was no biographical data about Y., not until now. From the title page of his play, one can see that he was a carpenter in Sokilen, Volin.

In 1874 in Zhitomir there was published his

The second eyzin [iron?] volume [rail]

from Zarbinits to Yurkats

by Chaim Yosilis, carpenter msokilen,

the first part, Zhitomir 1874.

The second part was published here in 1876.
 

The play is -- according to Y. D. Berkovitsh -- "a description of small-town beli-eglus, which had united in a "trust" to
struggle against the railroad. Written in a primitive folksy Yiddish, mixed with folk words and laws".

Sh. Niger, who wanted to see the play the fargeshikhte of elements of Sholem Aleichem's humor and cited additionally from the play with its type and verbatim, characterized Y.'s writing as such: "No true humorist (one artistically important of speech) is Chaim Yosilis, the composer of "Eyzin band", ever was. However it is in him and in his Yiddish and in his stories there exists any of the other love to perform with words, and from other gilut to push a joke that is, it seems, characteristic for Volin folks-yidn.

Niger also notes, after a book of Y.:

Welcome shftrni

The terrible journey from Zarbiney to

Borishev, limits in the middle of small

 towns small failure(?) s'h 5 miles --

was worth the eight-day journey rtsuf.

He who has made this among

iron volumes, this also has the book written by his hand, but that we

want to know the author so much --

he is R' Leib the writer [?]
