So sorry and sad to hear this. Leo was a person that I worked with and knew for more then 50 years. A man of vast knowledge and the skill level to accomplish what ever the task might be. I will miss him deeply along with the breakfasts we would go and have. To his family my prayers with God's help will help you get through this. RIP Leo your work on earth is done. God Bless.
