[4] Due to his father's own fame as a sculptor, for much of his early working career he is referred to as John Steel Junior.
[5] However, John Junior showed artistic talent, and despite this, the family sent him to study art at the Trustees Academy in Edinburgh, under Andrew Wilson.
As the office stood immediately opposite the Royal Scottish Academy it was quickly noticed by Edinburgh's artistic society, and acknowledged as a fine work.
[7] The first work to attract international attention was Alexander taming Bucephalus carved in 1832–33 (cast in bronze in 1883, and now standing in the quadrangle of Edinburgh City Chambers).
[14] His youngest son, Graham Steell[15] was a prominent British physician and cardiologist who is best known for identifying the cardiac murmur that bears his name.
His portrait was painted by Robert Scott Lauder and William Grant Stevenson (Aberdeen Art Gallery).
