  We continue the search for luminous blue variables (LBVs) in Local Volume
galaxies in order to study their fundamental parameters. In this paper, we
report the discovery of two new LBVs in the dwarf irregular galaxy NGC 1156.
Both stars exhibit spectral variability simultaneously with strong brightness
variations: $\Delta \text{R}_c = 0.84 \pm 0.23^m$ for J025941.21+251412.2 and
$\Delta \text{R}_c = 2.59 \pm 0.10^m$ for J025941.54+251421.8. The bolometric
luminosities of the stars are in the range of L$_\text{Bol} \approx (0.8 - 1.6)
\times 10^6$ L$_\odot$. These values are corrected for reddening A$_\text{V}
\approx 0.9$ and are given for the distance to the galaxy D=7.0$\pm$0.4 Mpc,
which we have measured by the TRGB method. Both stars are above the
Humphreys-Davidson limit in the region of relatively low temperatures,
T$_\text{eff} \lesssim 10$ kK on the temperature-luminosity diagram.
J025941.54+251421.8 had a temperature below the hydrogen ionisation threshold
at maximum brightness, exhibiting behaviour very similar to that of the known
LBV R71 during its 2012 outburst. We have estimated the masses of the detected
LBVs and studied the properties of their stellar environment. We discuss our
results within the framework of both a single star and a binary system
evolution scenario for LBVs.
