American International Group (AIG) is bringing in two senior leaders in London to join its global specialty business.

Making the switch from Argo, where he was chief underwriting officer international and active underwriter for ArgoGlobal Syndicate 1200, is aviation insurance expert Steve Eccles. The former Travelers Syndicate 5000 active underwriter will come onboard AIG April next year to serve as global head of aerospace, general insurance.

Eccles, who initially worked as an aviation broker before becoming an aviation underwriter at Lloyd’s of London, brings more than three decades of industry experience to the post.

Meanwhile James Langdon has been appointed as UK head of energy & construction, general insurance, and will be in charge of developing and executing the UK strategy as well as driving underwriting excellence.

Langdon will be joining in December from Chubb, where his more than 16-year stint there included time spent as global head of upstream energy.

“As we continue to develop the leadership team of our global specialty business and position ourselves for future growth, I’m pleased to appoint Steve and James to their respective roles,” said global head of specialty Peter Bilsby.

“Our clients and partners will benefit enormously from the wealth of experience they bring to AIG, as we build a market-leading global specialty business.”
