Step 1: Understanding the Concept: 
The question requires identifying the artist of the artwork. The style—stark, linear, and filled with pathos—is characteristic of a specific modern Indian artist renowned for his prints and sculptures on human suffering. 
 
Step 3: Detailed Explanation: 
The artist is Somnath Hore (1921-2006). He was a master printmaker and sculptor whose work was profoundly shaped by his experiences witnessing historical tragedies like the Bengal Famine of 1943 and the Tebhaga peasant movement. His series of works, including the famous 'Wounds' series, consistently explore themes of pain, struggle, and humanity. This particular artwork, 'Children', is one of his most iconic creations related to the famine. While Chittoprasad also documented the famine, this specific stylistic rendering is quintessentially Somnath Hore's. 
 
Step 4: Final Answer: 
The artist of this work is Somnath Hore.
