Mr Schaller was voted the most influential Protestant leader in America, ahead of Billy Graham, in a nationwide church survey, ahead of Billy Graham.
He wrote or contributed to nearly one hundred books on church problems, growth and leadership, selling more than two million copies.
In a recent book chronicling the life of Lyle Schaller, twenty-five pastors spoke of the way he influenced their lives and ministry.
The President of the National Association of Evangelicals, Leith Anderson, said in Christianity Today: "No one may have advised more churches in the 20th century.
"Many knew him as the consultant who came to their towns and churches to listen and recommend, averaging about 150 on-site church consultations per year.
"I don't know if the Guinness Book of World Records includes an award for the most parishes consulted, but Lyle Schaller would no doubt hold the record with thousands and thousands of visits to local congregations."
Dave Ferguson, a pastor in Chicago who's pictured with Lyle Schaller above, wrote this tribute on his Instagram account: "This visit was similar to many we had over the years where this brilliant futurist would describe in great detail the church of tomorrow.
"I remember one time he poked his finger in my chest and said: "Dave, the problem with you is that I have a bigger vision for your church than you do!"
"Thank you Lyle Schaller for years of wisdom and guidance. You made me a better leader. You will be missed."
