The firm was founded by Hannes Snellman in Helsinki in 1909. After the Second World War the firm started to grow. Hans G. Snellman, Hannes Snellman’s son, then took over and the firm attracted many family-owned and international, especially Nordic, companies as its clients. Many of these relationships have continued throughout the generations up until the present day. Johan G. Snellman, Hans G. Snellman’s son, joined the firm in the 1960s, and went on to become a partner and later an of counsel.
